Add simple unit tests to the Trove specs repo which ensure that
specifications submitted follow the template correctly and address
all the needed sections.
Update tox to run these unit tests automatically.
At the beginning of each release, test_titles.py will need to be updated
and 'current_release' modified to reflect the new release directory. At
the same time, the new release directory will be created, the index.rst
file in doc/source ammended to include this directory, and any unmerged
specs moved there. In this way, changes to the template will only
affect specs going forward and avoids having to modify any specs that
have merged in previous releases.
(It will also have the side effect of signalling the 'opening' of the
release to new specs.)
