Add util functions to compress and uncompress strings.
Fixed a couple of modules so they use SceneCommunicationService rather than directly call functions on the CommsManager.
* Enables regular jpeg map images to be served directly from the region.
* EX: http://192.168.1.127:9000/index.php?method=regionImagecc4583cd269b41bfa525dd198e19a5c5
* This is actually HTTP server address + port + index.php?method=regionImage<REGIONUUID, no dashes>
* The Webmap image location gets printed on the console when the simulator starts up.
* JPEG data is cached so we only create the webjpeg once.
* Implemented a hack so regions beyond the 10,000m range will show the map without having to click on the map before they'll start to show. The hack shows regions around the one you're in, but it won't show the one you're in.. you still need to click on the map to get that (not sure why yet). Additionally, the map still only shows pictures for regions that are hosted on the same instance (no change).
* Fixed a bug with Terragen loader where it would do bad things on a non 256x256 sized terrain. Now loads the array correctly.
* Moved MapImageModule.cs to Modules/World/WorldMap
* Changed Location.RegionHandle to use Helpers.GetUlong instead of doing it ourselves.
