Loading cropped parts of map elements, map reset tool in buildmode

[SECBATON-GRIFFON]

[content][administration][qol]

What this does

Adds parameters to map element loading that can crop the map at certain coords. (example loading X 2 to 4, Y 2 to 4 and Z 1 to 1) The "crop" doesn't move to the offset point, and it rotates with the map element if possible Also adds a buildmode tool to reset a selected portion of the current map to its compile state by reading from the .dmm (accessible by shift click toggling the basic/advanced buildmode button) May contain bugs caused by attempting to overwrite area-tied things like APCs or etc, so use with caution

Why it's good

Allows admins to easily restore a huge chunk of the station if they don't like someone's dudebombs or their own mistaken ones.
