Changeset 393 for veekun/trunk/root

Locations mini-commit.
- Redid location pages to match the new format.
- Removed incorrect header text from Pokemon pages.
- Fixed up EncounterSet?->simplest_method to return more display-friendly data (thus merging together buckets with the same rarity), and corrected the old documentation. Also removed old inaccessible code.
- Refactored sections into their own database table.
- Refactored method-cell code into its own macro.
