Training mission - SVN

Hey everyone, I've committed the first iteration of the training map to SVN. It's a simple layout using BSP shapes for now.  We can always do more variations of this map, it doesn't take too long.  If we decide to add our own custom art to it, the general scale and shape of each brush should be a good reference for our environment artists to go in and add their work.  Aside from buildings, we can do plenty of pipes/rooftop decorations for the obstacles.  Maybe if we're looking to save time, we can have the artists use existing work from their libraries, depending on what Dopefish wants visually. Update your SVN and try it out - let me know what you think.
