Added Reactive Teleport armour and on/off sprites for the armour.

Click in hand to toggle on/off (like a cloaking device).
When worn and activated, successfully blocked attacks will cause the wearer to warp randomly up to 8 tiles.
EMPs will disable it.
Values may need tweaking to balance the armour.
One set now spawns in the RD's office to it will get used/tested, depending on how that goes I may move it to being produceable by the protolathe only, or remove it entirely etc

Removed more X-Com shit I managed to fail to remove because of silliness with updating before committing restoring the file I meant to delete.

Updated the changelog.
