Various improvements to peripheral invalidation

Browse Source 
- Abstract peripheral ID and type checking into separate class
 - Update peripherals directly rather than marking as invalid then
   fetching from the network.
 - Update peripherals when adjacent tiles change

This does result in a slightly more ugly interface, but reduces the
amount of work needed to perform partial updates of peripherals, such as
those done by neighbouring tile updates.
