The Benjamoose texture update

Thanks to Benjamoose, we now have an array of new textures available for
the TARDIS. There are now selectable skins in the options, including
2005 Skin, 2010 Skin and the War Doctor Skin. There is also a toggleable
'snow' option to show our festiveness. The interior of the TARDIS has
also had a bit of a revamp, with the curved walls receiving entirely new
textures. Fixed the new entity door not letting people out when
isomorphic controls were enabled. Improved HADS detection and damage
screenshake. The exterior will no longer take damage while in the
vortex. Implemented new system for more easily and more flexibly
changing the teleport speed and sound. If the TARDIS has exploded, the
teleport speed will now match the increased pitch (and therefore speed)
of the sound. Moved the spawnmenu options to a seperate file for
convenience. Ragdolls now teleport as expected. Calls to TARDIS E2
functions are now covered by prop protection rules wherever necessary.
Updated Official TARDIS E2 to reflect new FastReturn function. Added a
sound for when phase is enabled. Improved SetGlobalSkin to auto add or
remove the lit sign or sticker.
