bg1npc.tp2 updates

Turning on Area Type Flagging for BGEE inadvertently turned on Miloch’s
script fix for mage14d.bcs, which doesn’t exist in BGEE.  Added GAME_IS
check for Miloch’s fix.

Fixed reference to file location for x#ajr1_bgee.are.
conv_tra.sh update

conv_tra.sh script was pre-pending utf8 to entire file path, e.g.
utf8/bg1npc/tra/english/*.tra.  Modified command to extract only
filename.
