Fix a few small issues with the progressive texture-download: 

- The initial priority wasn't passed in, so a discardLevel of -1 in the first
  request automatically cancelled texture-download.
- One-packet textures weren't handled, as CurrentPacket starts at 1 and
  StopPacket == 0 in that case.
- Increased MAX_ALLOWED_TEXTURE_REQUESTS to 15; incremental texture downloads
  will cause more requests.
