[CLOSED PR] Remove RCD from ghostdrones

[aft2001]

A separate RCD charge that isn't based on your internal battery, as well as significantly increased price of deconstruction of floor tiles, seems like a more reasonable solution. As an addition/alternative, just make deconstruction have a long cooldown, AND/OR give it a very noticeable progress bar and a longer (maybe 10 second) time period for you to have to stand still to delete a floor tile.
