Changes in this version:
- Unload areas that are no longer nearby, this reduces the amount of memory VP uses
- Support for 16-bit textures, uses half the amount of texture/video memory compared to 32-bit formats (does not work with Direct3D 11)
- Send message after 30 seconds of inactivity to keep connection alive(should help some people with frequent universe disconnects)
- Restore material after RWX ProtoInstance. This fixes some material errors like the white lane markings on grstreet1.rwx(should be yellow) and the incorrect colors on blip.rwx
- Fixed texture coordinates from RWX files not being loaded if they are after "#! Prelight" in the RWX file, like in ntree1.rwx
- Fixed url command not working when '=' is in the url
- Fixed incorrect loading of texture mipmaps in Direct3D 9 renderer, most often visible with masks
