Following commit 7510875, LaTeX2e no longer identifies packages by
pathnames, but by filenames. This breaks the inheritance mechanism
of fithesis and required copying university identifier from directory
names to LaTeX package filenames. More information is available at
https://github.com/latex3/latex2e/issues/510.

are no longer page-numbered, so that hyperref links work correctly.

`\thesis@selectLocale` is no longer performed globally for the
entire document during `\thesis@load` (effectively overriding the
user's hyphenation settings, if Babel's or Polyglossia's
`\languagename` differs from `\thesis@locale`). Instead,
`\thesis@preamble` and `\thesis@postamble` now locally switch the
locale and expand `\thesis@blocks@preamble` and
`\thesis@blocks@postamble`, which are the new redefinables. Since
this breaks the behaviour of `\thesis@blocks@mainMatter`, whose
effects would also be local, `\thesis@blocks@mainMatter` is now
executed directly by `\thesis@preamble` after closing the group and
becomes a new part of the interface between the class and the style
files.

As a preparation for the future inclusion of bibliography support,
the /csquotes/ package is loaded, `\thesis@<locale>@csquotesStyle`
is a new part of the locale interface that sets the /csquotes/
style of a locale, and `\thesis@selectLocale` now switches the
/csquotes/ style.

theses. Instead, the `\ifthesis@blocks@assignment` conditional can be
set either by the subsequently loaded style files or by the user. So
far, only the `fi` and `sci` style files set the conditional.

MUNI style files to set up colors of various typo elements.

user to have a separate Makefile for documents derived from example.tex.

Instead of defining `\thesis@[name]` within the `[locale].def`
files and `\thesis@[name]En` within the `base.def`
files, each [locale] now defines macros in form
`\thesis@[locale]@[name]` within their `[locale].def` files meaning
that English is no longer special-cased and multiple locales can be
loaded at the same time. This enables the model, where style files
conditionally load additional locale files (like `czech` and
`english` in case of the style file of the Faculty of Science,
which was the original motivation for the change).

The string manipulation macros `\thesis@`, `\thesis@@`,
`\thesis@@upper`, `\thesis@@lower` and `\thesis@requireLocale`
macros were also added to alleviate the complexity added by this
model. More specifically, the style files need to be able to
require new locales (this functionality is provided by the
`\thesis@requireLocale` macros) and strings of the current locale
can no longer be accessed directly through a command sequence, but
a command sequence must be composed from letter tokens and from the
expansion of the `\thesis@locale` macro (this functionality is
provided by the `\thesis@@*` macros).

The `\thesis@season` macro now returns a string rather than a macro
to allow for easy command sequence composition using the `\thesis@`
macro.

The `\thesis@requireWithOptions` was renamed to
`\thesis@requireStyle` as it resembles the semantics of the
`\thesis@requireLocale` macro.

The Faculty of Science style file now correctly typesets the front
matter in Czech and English regardless of the main locale.

The implicit options of the `mu/base` style file are now `nolof`
and `nolot` instead of `lof` and `lot`, respectively.

`\thesis@blocks@titlePage` definition.

`hyperref` is now loaded with the `unicode` option.

The `\thesis@blocks@titlePage` is no longer defined in `mu/base.sty`,
but in `mu/fi.sty` instead. In case of a rigorous thesis, an
advisor signature field is added to the title page.

The support for injecting the thesis assignment PDF via the
`assignment=path` option of `\thesissetup` was added.

One of the larger design decisions in this commit is the fact
that each locale string stored within a `\macro` macro needs to
have a `\macroEn` counterpart defined. Such a solution was much
easier to implement and document than special-casing and
documenting each string, whose English version was needed across
locales. The implementation comprises `base.def` files containing
the English definitions. These definitions are then automatically
imported by the locale file inheritance scheme.

Several new macros were added to allow for multi-lingual blocks:

 * `\thesis@authorEn`, `\thesis@advisor` -- They gets redefined
   via the `author` and `advisor` `\thesissetup` keys like their
   locale-agnostic counterparts, but the initial values are
   `\thesis@placeholders@authorEn` and
   `\thesis@placeholders@advisorEn` rather than
   `\thesis@placeholders@author` and
   `\thesis@placeholders@advisor`.
 * `\thesis@field` -- The field of study, required by the sci style
 * `\thesis@departmentEn`, `\thesis@programmeEn`, `\thesis@fieldEn`
   `\thesis@titleEn`, `\thesis@TeXtitleEn` -- The English versions
   of their locale-agnostic counterparts
 * `\thesis@abstractEn`, `\thesis@keywordsEn` -- These no longer
   default to `\undefined`, but instead use the fresh-defined
   `\thesis@placeholders@abstractEn` and
   `\thesis@placeholders@keywordsEn` locale macros.
 * `\thesis@date`, `\thesis@year`, `\thesis@month`, `\thesis@day`,
   `\thesis@season`, `\thesis@academicYear`, `\thesis@semester` --
   These are all parsed out of a single value assigned to the
   `date` key via `\thesissetup`.

Added the \thesis@TeXtitle private macro.
