Adds MockUserAccountService and connects it up
Stops services being carried over between tests since this leads to hard to find bugs
Improves information and error reporting when loading plugins
* Moved the SL asset type to content type conversion methods from ServerUtils to OpenSim.Framework.SLUtil
* Linked content type to asset type in AssetMetadata
* Restored HG inventory access which had been lost upon adding a 3rd argument to inventory and asset server handlers
* Fixed a stupid bug in the InventoryConnector which was making move items do things twice
* Shrinks the largest in-memory object, the LLRAW.HeightmapLookupValue struct (only used for exporting to LLRAW terrain files), to the minimum possible size. This seems to have the odd side effect of cutting the size of the two double[256,256] terrain objects in half. Possibly an alignment optimization?
Several improvements in the connectors themselves.
Several improvements in configurations.
Needed to add a hack in IUserService and UserManagerBase, to be removed when that service is refactored.
