Add transit tubes to the RPD

[duncathan]

I'm planning a rewrite for these pieces of shit, and wanted to see how the public felt about adding them to the RPD. It'd encourage their use (I don't really know if this is good or bad) and would be no more capable of lading down dense objects than it already is (fucking disposal chutes.)

When the transit tube dispenser first got added there was a huge explosion of its usage for like a couple weeks then never happened again, I imagine the same thing will happen again.

Transit tubes could use some love as they stand. It would be nice to see the player sprite inside the tube as it moves.
