Forcefield cannot be removed while holding an offhand item; Forcefield controller duplication glitch.

[Jexperto]

Summary:
Shift + Right Click while holding an item in an offhand doesn't remove a forcefield, but instead remembers block as one of the positions.
Creating other forcefields with one of the positions being a forcefield panel sometimes results in forcefield controller duplication.

Tested on DDSS modpack.
