- Increased precision of texture scaling factors to full fixed point. In the process

Browse source 
I got rid of the old tx and ty CVARs because they made the texture scaling
  much more complicated than it was actually needed (and besides, they were completely
  useless except for testing purposes anyway.)

- Increased precision of texture scaling factors to full fixed point. In the process
I got rid of the old tx and ty CVARs because they made the texture scaling
much more complicated than it was actually needed (and besides, they were completely
useless except for testing purposes anyway.)
- Added a simple check for abstract weapon classes so that I can properly define
the DoomWeapon base class.
- Fixed: When the Tome of Power runs out it must also set any pending weapon
