Upgrade MobileUO to CUO version 0.1.11.0

This PR is bringing CUO up to version 0.1.11.0. 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.

This took a lot longer due to a number of rendering changes - I had to incrementally go through the commits instead of my usual version big-bang.

Changes since 0.1.10.0 PR: https://github.com/mandlar/MobileUO/compare/21d1b6f2...2b5a9bcf

• Added a new splash background
• Alpha layer was inverted between 0.1.10.0 and 0.1.11.0
• Symlinked all files that have no changes from CUO version. Once we get to latest version, I'll probably drop the symlinks
• Rendering was changed to use render lists per statics, mobiles, effects and transparents. I couldn't figure out how to get a depth stencil to work Unity, so I instead merged all the render lists into one and do my own z-depth sort on the entire list. This fixed the issue I had where mobiles were walking on roofs, etc. The performance seems to be okay on my phone (30-50+ fps, depending on number of objects on screen), it can be re-visited again alter.
  • Additionally, if you write vertex's beyond 100 on the Z plane, they won't render in Unity. I don't know why, it feels like there is some sort of clipping plane going on but this is beyond my knowledge. If you look in Unity Batcher I have some debug flags that shows this behavior. If you divide the Z values to get them under 100, it works. But that doesn't fix the depth rendering. However, it isn't needed with my above z depth sort for rendering. We only need to figure this out if we want to get CUO's multiple render lists working. Someone smarter than me can figure it out 😄
• I re-added the Pixel checks to make coarse Item gump selection to work again
  • I also added it to ItemView so that the same behavior works on items on the ground!
• 0.1.11.0 added TextureAtlas (sprite sheets). It'll generate the sprite sheets correctly, but I'm having issues with it loading the textures from it. So for now, I changed it to where each sprite sheet is just one sprite (which works correctly) and will re-visit later
• Unity Batcher:
  • As mentioned above there is some sort of issue with anything drawn above Z 100 and I added debug flags to show that
  • All of the drawing methods were re-written in the CUO batcher. I kept some as deprecated because they were used by the Assistant, so they'll need to be fixed later
  • I turned off UseGraphicsDrawTexture flag. Everything now uses vertex to render. The previous Unity graphics way was causing some weird textures getting flipped vertically
• XNA:
  • Replaced Color with latest FNA version - this fixed a lot of color issues
  • Added TextureSize and Brightlight to Effect
  • Added SpriteEffects

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