v68 - important bugfixes

SORRY FOR THE MESSED UP HOTFIX IN v67

and so many thanks to blackjackGT for rigurous playing and sharing bug reports and feature suggestions. This helps a lot.

-fixed the missing surface bug which would result in the player getting tuck and weapons not showing up during aiming

-fixed the screenshake bug that would push the view outside the map and stay there

-"feature": you now keep the weapon you currently have even when you use ALT or ESC to Skip or Restart the room, makes it easier to collect the pistol from the first enemy and then skip to later levels (i will make a cleaner solution for this once the level select screen is ready).
