since docutils 0.10.
This adds support for internationalization: our code supported only

Now websupport modules has separated and move into
sphinxcontrib-websupport package. They are also tested in the
package. Hence, we should test the bridge code for them.
* 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
