fix of inability to build planned things individually in some circumstances

+ Colour themes of planned objects
+ Some work for controller planning
+ Fireflies easier to click
+ Show planned figure immediately after it was selected from the menu
+ Performance improvements (planned figures will not be animated as real things)
+ Redrawing planned walls on camera rotations when game is paused
+ Hint message when planning
+ Space bar planning (one press to select the starting point, second to select the ending)
+ Game crafting menu scrolls properly in paused mode
