printed or the digital versions of a document.

`\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.

were renamed to `\thesis@<locale>@spring` and `\thesis@<locale>@fall`.

The semantics have also changed. The `\thesis@parseDate` macro no
longer sets `\thesis@season` to `winter` if `\thesis@month` < 7 and to
`summer` otherwise. Instead, the `\thesis@season` macro is set to
`spring` if 2 > `\thesis@month` < 9 and to `fall` otherwise.

The `\thesis@academicYear` macro is no longer set to
`\thesis@year`-1/`\thesis@year` if `\thesis@month` < 7 and to
`\thesis@year`/`\thesis@year`+1 otherwise. Instead, the
`\thesis@academicYear` macro is set to
`\thesis@year`-1/`\thesis@year` if `\thesis@month` < 9 and to
`\thesis@year`/`\thesis@year`+1 otherwise.

These changed month ranges reflect more accurately the beginning and the
end of the spring and fall semesters.
