Dweller 1.17.4

Yet another bug fix release. This time I did however also add a few new rooms to the dungeon.

#166 Wands and scrolls were limited to a maximum range of 1
#168 Scrolls used on inventory (enchant, recharge) gave an out of range message
#167 Targeting reticle still being drawn after disarming a trap/closing/opening a door
#169 Add more room designs to the dungeon
#170 Fix problems with target cycling, target reticle and messages
