These patch should allow people using systems that do not have their locale set to En_US or similar to use OpenSim without suffering effects such as being a million miles up in the air on login.
The problem was caused by parsing strings without forcing that parse to be En_US (hence different decimal and digit group symbols were causing problems).
Thanks very much to VikingErik for doing the legwork on this fix and phacelia for spotting it in the first place.
* Added new generic "Location" class to handle 2D integer locations. Going to use it to replace all RegionHandle and X,Y coordinate references throughout the entire project. You have been warned.
