This commit fixes the bug of being able to steal a tram's controller,
because it was not anchored. It also adds two new things and a minor
refactor to the "allowed-to-move-this-even-if-anchored" system, chairs,
windows, and grilles.
This commit adds an MT/TS to the research department, changes the names
and descriptions of the tram parts to have a little more care, and
slightly fixes the rail icon.
This commit converts the MT/TS control system from a debugging move panel
to a on-rails system. The controlpad has been repurposed as an on/off
button.
