squashed a bug

fix crash when a construction changes its id and its popup remains open (eg constructions connected to freestyle stations)

Introduced scale, skew, undo + some small tweaks

better blacklisting + better absolute NWSE

make compatible with Werner's mod + make construction updates optional

add option to move constructions along absolute coordinates, ie ignoring the current camera view.

filter the constructions to be made moveable

upgrade to move more constructions - no crashes unlike the copies!

made compatible with a new construction soon to be released

fine adjustments are now twice as fine
