Support for 1.0.9

[Massimo]

This is Trac 1.0.9 with nginx and uwsgi.

I have built both plugins from the latest svn:

-rw-r--r--  1 trac trac 9,5K Aug 29 13:42 TracIncludeMacro-3.0.0.dev0-py2.7.egg
-rw-r--r--  1 trac trac 8,6K Aug 29 13:49 IncludeSource-0.1-py2.7.egg

However IncludeSource-0.1-py2.7.egg coming from this plugin IncludeSourcePartialPlugin is not recognized by Trac, it does not appear in the Admin plugin list or in the /about. The [[IncludeSource...]] macro does not work. The other works fine. But I definitely need to define parts like the usage() body of some source code files I like to quote in wikis.
