- first batch of adjustments to the new tile management.

- consolidated Polymost precaching and removed precaching for static tiles because they now are always loaded.
- removed cache configurability. On modern systems this is relatively pointless - allocating 50 or 100 MB is a non-issue - and the cache is due for replacement anyway.
