v1.19 small update for 250 battle achievement, couple small fixes

-added dialogue option for completing the 250 battle achievement from the final scene (talk to the elf queen)
-fixed bug on character group overview that showed the blank white tooltip for attack and ranged attack (if you have a bow equipped)
-fixed bug with help instructions were sometimes not displaying properly when holding the help key. The Help key (default keyboard key is "H") will now toggle the instructions on/off instead of the old hold on to view method. The menu key will also toggle the instructions off (default keyboard key "ESC").
