Final fixes to kickstarter demo (unless something gamebreaking appears)

* Fixed isue with level 5 where you couldn't continue 

* Healing items now ewuip automatically if available

* Healing items can't be used if life is full

* Combat now is more intuitive no I frames for enemies

* Reaction time after attacking restores faster

* Dialogs now can be completely turned off (except for the boss I like that one)

*  No fix to knockout animation that one is funny too
