tigefa4u projects Trac

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

Updated wiki pages and bumped version number.

Trac requires Python 2.3.

s/GPL/BSD

Updated RELEASE, README and ChangeLog

TracCrossReferences branch: some renamings

Note: if you already had a `xref` table, simply do the following in sqlite:
{{{
#!sql
drop table xref;
update system set value='13' where name='database_version';
}}}
Then, using `trac-admin`, do an `upgrade` and an `xref`.

PS: also fixed the upgrade process (one statement at a time)

add .vb to the recognized extensions for Visual Basic highlighting (fixes #1711)
