Bugfix for this issue https://github.com/TD-Addon/TD_Addon/issues/137

Fixes to a number of Bellman scripts, to prevent the spawning of illegal papers and allow papers to be properly taken out of rotation.

Turns out variable values persist even if you StopScript a global script, which is a pain, but has now been dealt with.

Also corrected five Bellman entries that were missing a <br> somewhere.

Looking through the BSA, I noticed many of the textures were saved in A8R8G8B8 format or were uncompressed. I converted these textures to DXT1 or DXT5 as applicable.

Added NCO and Merged Trishapes. All done in nifskope, so didn't change anything on the models.
