Describe Doxygen-specific %features in a single place.

Put them all in a single table instead of describing doxygen:notranslate
separately for Java and Python when it does the same thing for both.

And while doxygen:nolinkranslate and doxygen:nostripparams are currently
Java-specific, it probably won't remain this way and these features would
either be made to work for Python as well or, perhaps, removed entirely.

-There is a switch '-doxygen' in every module that supports converting

-manually overridden by specific swig's features,
-like <i>feature:docstring</i> or <i>feature:autodoc</i>, in this cases
-Doxygen comments have lowest priority.

-If Doxygen parsing is switched off, then all the comments are stripped
-out in parser and all the resources used by comment parser and
-translator are freed.
+Doxygen comments translation is disabled by default and needs to be explicitly
+enabled using the command line <tt>-doxygen</tt> switch for the languages that
+do support it (currently Java and Python).
