Unknown attributes "touristok," "uv," and "abandonedbuilding"

[twlare]

When using cache.load(), you get a warning if the cache has attributes touristok, uv, or abandonedbuilding.
GC3C9R5 results in: WARNING:root:Unknown attribute touristok, ignoring.
GC3DWVF results in: WARNING:root:Unknown attribute uv, ignoring.
GC54BGE results in: WARNING:root:Unknown attribute abandonedbuilding, ignoring.

The fix is to change _possible_attributes{} in cache.py to use the lowercase version of the attribute:
"AbandonedBuilding" should be "abandonedbuilding"
"UV" should be "uv"
"touristOK" should be "touristok"
