* change: specifically setting empty comms_log_gui & message_gui sections inside hud plists now resets those guis to Oolite's default. Updated standard huds accordingly.
* bugfix: fixed crash with malformed gui declarations inside hud plists - trunk & maintenance.
* change: internal name of commodity identifiers normalised: 'liquor/wines', 'alien items', 'gem-stones' are now expressed internally as 'liguor_wines', 'alien_items' and 'gem_stones' - in most cases the old identifiers are still recognised, for backward compatibility.
- linux build and windows build directories separated, both can now share the same source directory without build conflicts.
- updated copyright notice in shaders files, minor planet drawable cleanup.
