bspguy v2

New:

• Added simplify command for further reducing clipnodes.
• Added delete command for deleting BSP models.
• Added -optimize flag to the merge command. This reduces usage of all data types.
• -hull 0 can be used with the noclip command. Deleting hull 0 reduces usage for all data types except clipnodes.
• Added -redirect option to the noclip command. This redirects a clipnode hull to another one instead of disabling the hull entirely. This allows players/monsters to interact with the target model normally, but with less accurate collision.

Improved:

• -nohull2 redirects hull 2 to hull 1 instead of disabling hull 2 entirely. This results in the same reduction of clipnodes while allowing large monsters and pushables to function normally (but with less accurate collision).
• Unused data is deleted when merging or deleting model hulls.
• Huge reduction in visdata size when merging (~2.5 MB -> ~0.01 MB on an echoes merge).

Fixed:

• Fixed broken collision/faces on some entities (#1).
• Fixed duplicate textures in output file when merging (#2)
• Fixed crashes merging visibility and resizing lightmaps on some maps.
• Fixed info_nodes being deleted when merging.
