routing: Cleanup URL routing and improve page matching. * Add new types of route parameters for integers (int4, int2, int). * Remove hard-coded hacks around converting year/month/day values. * Make the blog post routes use the new typed parameters. * Fix problems with matching routes with integer parameters when they can get confused with a sub-page number.
