A bunch of level editor fixes in this one. Fixed bugs: [list] [*] Leaving the level editor with the "flatten area" window open could crash the game [*] Moving a landscape flatten area in the level editor would not automatically regenerate the landscape mesh [*] If no lights were defined for a level (e.g. unfinished maps in mods or similar) the game could crash on entering the level [*] The circle around SafeArea buildings was not rendering correctly in the level editor. [/list]
