Expose peripherals as a capability

Browse Source 
This registers IPeripheral as a capability. As a result, all (Minecraft
facing) functionality operates using LazyOptional<_>s instead.

Peripheral providers should now return a LazyOptional<IPeripheral> too.
Hopefully this will allow custom peripherals to mark themselves as
invalid (say, because a dependency has changed).

While peripheral providers are somewhat redundant, they still have their
usages. If a peripheral is applied to a large number of blocks (for
instance, all inventories) then using capabilities does incur some
memory overhead.

We also make the following changes based on the above:
 - Remove the default implementation for IWiredElement, migrating the
   definition to a common "Capabilities" class.

 - Remove IPeripheralTile - we'll exclusively use capabilities now.
   Absurdly this is the most complex change, as all TEs needed to be
   migrated too.

   I'm not 100% sure of the correctness of this changes so far - I've
   tested it pretty well, but blocks with more complex peripheral logic
   (wired/wireless modems and turtles) are still a little messy.

 - Remove the "command block" peripheral provider, attaching a
   capability instead.
