Marek Kubica's patch to find templates installed by easy_install

Adds one more place to look for templates. We already look in several
places, trying to find them. This adds one more. When you install via
easy_install the hierarchy ends up looking like:

/usr/lib/python2.5/site-packages/roundup-1.3.3-py2.5.egg/roundup/admin.py
/usr/lib/python2.5/site-packages/roundup-1.3.3-py2.5.egg/share/roundup/templates/*
