doxygen: Added option to compile specific directories

The doc/Doxygen/Allwmake script can now be given directories as
arguments, which will be built instead of the usual src/ and
applications/ directories. This allows testing the documentation of a
limited set of files without building everything.

The outer doc/Allwmake script has also been deleted.
