Properly handle project-root url when mapping PATH_INFO (when path_info == [] the request should be for /)

Follow-up to r4794, fix corresponding test.

''Alternate format'' links are now `rel="nofollow"`. Reduces server load for essentially redundant content.

Some little cleanups in the Wiki module.

Proper default value for templates_dir to keep it from messing up trac.ini; make config parser work for relative paths in values

Fix rendering of the project index, in case ClearSilver is not installed. Reported live from PyCon by thatch, thanks!

Optimize a bit the !GenshiHtmlFormatter.

The diff templates are reused across different sub-systems, so move them back into the common templates folder.

Remove obsolete setuptools branch.

Split up template directories so that the templates inside the packages of the sub-system they're used by.
