Allow targeting mobs without attacking like real RPGs. To start auto-attacking/following a mob, a player has to press T. ESC clears current target.
Change map info coordinates to gridX and gridY instead of real x,y and also align it to the right
Fix inventory button to its temporary skin (the achievements one); Add tooltips to bar buttons
Make thrown items disappear like normal drops
Add spells effects to the game. A proof of concept implementation (very lacking!)

* Using items to draw spell effect. To be replaced with actual spell entities.
* 3 types of spells - AOE, single target, directional.
* Until a client spellbook implementation they are hard coded into the skill bar (and may be refreshed by pressing F)
* Game handling of removed items is HORRIBLE - instead of marking the entity as removed, it is searching for them in the grid. A partial fix was implemented, will improve later on.
