Added towny support

- Players can only create shops in shop plots, not in wilderness or normal
  plots
- Added permission "shopchest.extend.protected"
- Changed permission "shopchest.extendOther" to "shopchest.extend.other"
- When creating a shop on a double chest, both chests must not be
  protected/in a protected region
- To extend a shop into a protected region (e.g. WorldGuard/Towny), you
  need permission (shopchest.extend.protected)
- Added no-permission message for "shopchest.extend.protected"
