Upgrade MobileUO to CUO version 1.1.0.0

#24

This PR is bringing CUO up to version 1.1.0.0. This build seems stable in both Unity Player and my Android phone from my testing. Again, there could be issues that I haven't noticed.

The biggest change of this version was switching away from static World to it being passed in everywhere. This heavily affected a lot of Assistant code - so there could be some issues there (but the Assistant was only in a half-working state to begin with).

Changes since 1.0.0.0 PR: https://github.com/mandlar/MobileUO/compare/635ee1c2...bc8edf9

MemoryExtensions don't seem to exist in Unity, so I had to fix BwtCompress to do a sort on Span via an array sort. Similar issue with NativeMemory in PluginHost - I commented it out for now

Everything else is base CUO changes. These were all the significant issues I encountered.
