Displaying categories by priority provides editors with better
guidance about what to spend time on. The Linter help page provides
more information about why the specific priorities have been chosen.

Categories can now have a severity level of "error" or "warning"
designated, which places them in a different heading on
Special:LintErrors.

Test plan:
Type "Special:LintErrors/" into the search box, and see that the
autocomplete dropdowns include the subpages for individual error
categories.

Instead of having a complex auto-increment category manager that had
additional caching, just hardcode the (currently 6) ids for each
category, which allows us to simplify a lot of code.
If Parsoid sends a lint error in a category that we don't know about, it
is silently dropped.

linter_cat is now an int ID that points to a row in the new
lint_categories table.
The mapping between category names and ids is all handled in PHP, and
cached in APC.
Note that you will need to drop the `linter` table manually and re-run
update.php for this to take effect.
