addons: Change shebang to use Python 3 instead of Python 2 (#2361)
Use Python 3 instead of Python 2 if addons are executed directly.
Running cert.py and misra.py against test/cfg/std.c.dump shows that
Python 3 needs only half the time compared to Python 2. I have tested
it repeatedly and the results are always the same. This is no surprise
at all. The memory footprint is very likely also significantly better
but i have not tested it.

GUI: projectfiledialog.ui: Add note about addons requiring Python (#2364)
This fixes https://trac.cppcheck.net/ticket/9456 (Tell the user that the
addons require Python) regarding the GUI. Whether it is useful/necessary
to add something similar for the CLI must still be checked.

manuals: Fix missing/wrong table of contents in HTML files (#2360)
The YAML setting `toc: true` works for PDF creation but for HTML it
simply prints `true` as the table of contents.
It looks like a misconception and the only acceptable solution I have
found is to use `--toc` on the command line instead of the `toc: true`
setting in the YAML header.
It is a known issue, here are more details:
https://github.com/jgm/pandoc/issues/2872
With this fix I get table of contents not only for PDF but for HTML too.
The PDF looks like before for me, the table of contents and the outline
are still present as it was before.

Georgy Komarov 3bd126486f addons: Clean up and clarify addons usage. (#2359)
* addons: Add '--recursive' arg. Clean up and clarify errors messages.

This commit introduce '--recursive' option for cppcheck addons.
Iff this option is set addon will recursively traverse directories in
given input files to find files with '.dump' suffix that would be
checked. Otherwise it will treat input directory as error (current
behaviour).

Add additional error handling with more clear error messages, clean up
the code.

* Add regex specifier

* Roll back --recursive option

* Update addons section in manual

IOBYTE 3a617fa04a Fix #9472 (Syntax error on valid C++ code) (#2363)
There are probably a lot more valid code patterns that generates syntax
errors so I added "operator" to the error message to make it easier to
find them.

PyCharm inspection warns for argument `visited=set()` with
