- Added a multitude of flags for A_Teleport.

Browse source 
- TF_KEEPVELOCITY: Keep the velocity after teleporting.
- TF_KEEPANGLE: Don't use the special spot's angle.
- TF_USESPOTZ: Normally, this function
- TF_NOSRCFOG: Don't leave fog at the previous location.
- TF_NODESTFOG: Don't leave fog at the arriving location.
- TF_USEACTORFOG: Use the actor's TeleFogSourceType and TeleFogDestType properties.
- TF_NOJUMP: Don't require or cause a jump. In this case, put 0 (or "") in for the jump destination when using CustomInventory items to teleport actors around.
