Added new target for makefile: modules-doc. Can be used together with include_modules

and exclude_modules to create doc files in the supported format.
Added new option to make: doc_format=format, where formats can be txt, html, xhtml, or
pdf.  Default format is html.
Updated proper and clean targets to also include module doc dirs.
Example: make exclude_modules="something" doc_format="txt" modules-doc
