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

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

The `\thesis@declaration` macro was added.

Added `\thesis@head`, `tail`, `author@head` and `author@tail`.

The `\thesis@authorEn` and `\thesis@advisorEn` macros are
unnecessary and can be emulated via

  `{\def\thesis@lang{english}\thesis@author` or `\thesis@placeholder}`

for an arbitrary language.

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

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`.
