When UPDATE_FAILED=true, failed tests will update the prototype PDFs

\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`.
