New doxygen script

[Alex Merry]

Hey Aurélien,

I wrote a new script to generate apidocs.  It's in Python rather than
shell script (because (a) yay for proper programming languages and (b)
cross-platformness).

If you run it on a framework like KCoreAddons, you'll get actual bona
fide apidocs (unlike if you try to run doxygen.sh on it).  It even pulls
in README.md as the main page text.

It can be found in kde:clones/kapidox/alexmerry/kapidox on the
frameworks branch.
