Adds docking controllers

Squashed 10 commits:

Adds simple docking controllers

Adds docking_controllers.dm

Moves docking handshake code into its own type
Keeps docking code separate from the code for messing with airlocks and
doors.

Improves handling of invalid states

Adds docking controller to research shuttle dock

Also adds the start of a nano-ui template.

Resetting the dock controller resets the override

Adds debug verbs

Adds support for overriding docking checks

Less confusing name for the docking program
