New approach to the low-res problem. Basically, we already have a 1024 minimum, and the tallest maps are restricting themselves to 2048 maximum. All backgrounds are scaled down 50%, then scaled up on draw. Saves memory, and backgrounds are already deliberately fuzzed for depth of field anyway.

Partially reimplement joining rooms

update the project to ios4 by removing pre-3.2 references add missing lowres image other smaller fixes

ok really fix the command line utility
