Update version check for KSP 0.24.
Update resource tweaking for 0.24.

UIPartActionResourceEditorImproved.OnSliderChanged seems to be a copy of

GameEvent.onEditorShipModified event (and updates the displayed value).

This fixes the breakage of the vessel cost widget when adjusting the amount
of resource in a part in the editor.
