An ability to set the interior location manually.

[VelonacepsCalyxEggs]

I found, that a lot of performance is being eaten up, just by rendering the interior model, especially on open maps, where most of the map is an open space. I propose an ability for mappers, to add a file in /garrysmod/data/tardis/positions/[map_name]/position.txt that will contain coordinates for the tardis interior. This will allow mappers to create blank rooms [4096 * 4096 * 4096 hammer units (should be enough for most interiors) ], where the interior's model can be spawned by the addon, improving overall optimization.
