* rename a few test modules to make the names more consistent
* do not copy/use Sphinx from build/ (unnecessary without 2to3)
* use a temporary dir for *all* test projects, the source tree
will stay pristine that way (default is tests/build)
* speed up tests by ~3x by splitting up test projects and avoiding
rebuilds
"simple" item lists are not compacted. See
http://docutils.sourceforge.net/FAQ.html#how-are-lists-formatted-in-html.
Bullet lists like the "Indices and Tables" section look odd when they are
not compacted. Therefore specially change any bullet list that only has
paragraph's with pending_xrefs to use compact paragraphs instead.
Implemented secnumber_suffix conf.py option. Default is '. '. Section
numbers look better if changed to u'\u00a0\u00a0'.
