Fix StudentTable and StudentTableCount

[smurthys]

Commit 9765503 fixes #181 and #182

• View StudentTable now returns both user name and schema name, and it works on all tables and views students own independent of schema name and ownership.
  • It now uses pg_catalog instead of INFORMATION_SCHEMA, because the latter does not provide all the information needed
• View StudentTableCount now returns user name and just reuses view StudentTable
• Columns in both views now have appropriate names
• General: adjusted line spaces and put ownership grants first in permission blocks.

Thanks @srrollo and @afig for the review.

Commit 7e9712a gives the count(*) column a name in view StudentTableCount.

BTW, the file in question has a few minor issues with line lengths, etc., but those things will have to wait.
