Updated .gitignore to ignore .swp files and the old symlink.
Removed some unused imports from the forms controller.
Added an ``__all__`` list to ``model/__init__.py`` to make Pyflakes and autocomplete happy.
Changed the collection backups test so that the orderBy tests were using ``id`` values and not ``datetimeModified`` values since the latter have identical values when using MySQL and programmatic updates.
Test functionality is now located in the ``tests/__init__.py``, primarily in the ``TestsController`` defined there; that is, each test module no longer needs to define ``self.extra_environ_admin``, ``tearDown``, etc.
