See https://github.com/plk/biblatex/issues/1058 and
https://tex.stackexchange.com/a/581469/70941. The hotfix should be
reverted after BibLaTeX v3.17.

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.

This reverts commit 1f3cd34795db6fcbfdc94cd22772bc4dc24f392a.

The patch was submitted by Juraj Pálenik.

This conditional determines, whether the scanned assignment
specified by the `assignment` key is going to be hidden in the
digital version of the document. It is by default, but some style
files (`/mu/sci`) switch this, so that the scanned assignment is
included in the digital version.

The output of \thesis@block@assignment and \thesis@@{assignment} now
depends on the value of the new \ifthesis@digital@ conditional.

The tocdepth now uses the standard numbering (\part has tocdepth of -1).
Added a visual test suite.

\MakeUppercase is now disabled in PDF text, which fixes the \part error.
\tableofcontents folding now works as indended for -1 <= tocdepth <= 4.

Removed \paragraph entries for tocdepth>4.
Chapter entries are vertically spaced for tocdepth>1.

`\thesis@blocks@clear\tableofcontents` in `\thesis@blocks@tables`.
