Test that grammars.yml agrees with the list of submodules

Browse Source 
If any submodules are missing from grammars.yml, or are listed in
grammars.yml but missing from the repo, the test will fail.

Eventually it would be good to test that the scopes for each submodule
are accurate, but that will take some more work.
