Many fixes for markup validation errors. Should close #1927.

for better modularity keep `TREAT_AS_BINARY` inside the `PlainTextRenderer` class

Prevent exception being thrown in Pool.__del__ on application shutdown due to self._core being have destroyed by stuffing the three needed methods into the Pool class object. The apr_initialize call in Pool.__init__ has also been moved into a more logical place to ensure it gets called before svn_pool_create when creating the application-level Pool object.

Add TracPlugins to default pages.

The plain text renderer would normally render as text anything that's not binary.

However, there are a few formats (mainly PDF, RTF, etc.) that are not
detected as binary, but not human readable either...

For the time being, we maintain a list of this kind of format
which should be treated as binary.

Fixes #1920.

Added trac.fcgi to MANIFEST.in
