fix build and permissions problems when launching hwengine from command line

merge+smallupdate

Reimplement room creating

use the cmake built-in ts->qm conversion instead of keeping binary files in trunk

memory management for openalbridge added openalbridge as dependency of hwengine usound formatted clearly

disable uSHA, enable adler32

merge

Replace SHA1 with adler32. For simple purposes of checking to see if players are playing the same map, this should be quite adequate and runs 15 times faster.

some memory caring code

This reduces CheckLand ~5.5% on average over prior making the overall reduction ~77.4% instead of ~81.9%. It does skip centre pixel in odd w/h, but that really shouldn't matter much in this case. Can alter if any objects are noticeably off.

fix zoom smoothness some more work for weapons on the ifrontend bugfix for the gameconfig page

add initial stubs for selecting weapons in the ifrontend

Remove redundant test, add some temp variables to speed up the expensive CheckLand

add local rev number/rev count to dev version suffix
