Fix movement glitches for actors with low speeds (e.g. a rat).  Was caused by false detection of being stuck.
Actors are moved on if idling near a closed interior door.  Unreachable pathgrid points due to a closed door are removed from the allowed set of points.
Fixed issue where allowed nodes were being erased. PathFinder was returning an empty path if the closest pathgrid point to the start was also the closest pathgrid point to the goal.  Still need to clean up and remove logging statements.
Cleaned up logging statements.
More cleaning up.
Suppress compiler warning.
Forgot to add a guard :-(
Fix typo in a condition.
Fix older savegame compatibility regarding new crime feature.
Crime: mark witnesses as alarmed.

Fixes guard dialogue to properly detect if the player turned himself in.
Add some missing SDL to MyGUI key translations.

Most importantly to allow numpad enter as alternative to return key.
