* Fixed some of the problems with crossing regions when flying: you should no longer sink to ground level when crossing (should keep roughly your right height). Should no longer sometimes get sent back to the centre of the current region when attempting to border cross. But instead sometimes you will find you avatar stop at the edge of region and you will need to start moving again to retry the crossing (which should then work). This code is partly based on Babblefrog's issue #212 patch. [I think I have some ideas of how to solve the stopping at edges problem, just want to get the inventory code done first]
* Capabilities code has now been moved to the OpenSim.Framework.Communications project as some of the caps code will be tightly tied to inventory/asset handling and it was causing a two way reference problem when it was in its own project/dll.
This is a Big commit as I was going to keep my inventory work local until I had it in a working state, in case it brakes anything, but its getting harder to keep in sync with svn.
* Updated SimpleApp with various introduced dependencies
* Extracted ScenePrescence creation in Scene
* removed try-catchall from UserManagerBase (that actually hid a bug)
* Refactored RegionInfo
* handle is calculated
* it will explode upon accessing x,y,ip,port,externalip if not explicitly initialized
* Removed superfluous 'ref' keywords
* Removed a shitload of 'catch Exception e' that causes build warnings
* Lots of small refactorings, renames et c
* Ignored some bins
