When UPDATE_FAILED=true, failed tests will update the prototype PDFs
instead of terminating the procedure.

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`.

updated the `README`.

The `make all install-base` command can now be used to perform just
a base installation. Using the `make docs install-docs` command
afterwards will typeset and install the documentation as well.

The `test/` directory is now also uses the `university/faculty` path
scheme employed by the rest of the package.

The links within the index all pointed to the title page.

As a result, hyperref links to appendices are no longer broken.
