More fixes and edits!

* Fixed a bug with client_exit module button appearing on full reload.
* Fixed the battle window to work properly now (left click: attack, right click: menu).
* Added auto walk checker for more accurate aut walking:
  - It will always find the path now, except in rare occasions gets stuck running back and forward
  - Re-calculates path every 10 steps and also when you hit an object that cancels your step.
  - Right now this is just a temporary method.
  - Cancels the checker when you move or press escape (has to be done client-side).
* Added a new setting to UIComboBox class 'mouse-scroll' to enable/disable mouse wheel scrolling.
* Added support for no ping in cooldowns.
* Added missing PlayerStates (hungry and bleeding).
