Frontend: * Disabled frontend's hog count for now to fix issue #44 - doesn't have to be limited to 48 anyway (but a limit based on active map would be nice)

Frontend: * Updated random map selection: Clicking on the map preview will now create a new random seed and pick another map of the current type selected (random map, random maze, mission or static map)

Frontend: * Added small icons to theme selection as well (open for discussion - like it or not?)
