Did a lot of ripping things up. Now all the UI drivers are compiled for all platforms (and nonsense ones, like ui_carbon.c on, say, Windows, will be one-fuction stubs), and the appropriate one is chosen at startup. This lets us pick a GUI one by default, but fall back to stdio if there's an initialization issue or the let the user pick stdio because he's ssh'd to a headless server, etc). It also lets us plug in a Qt and GTK and blahblahblah UI on linux and let everything coexist in one binary. Also, a lot of the bad abstraction breakage in platform_unix.c that got wedged in there when this was a Mac Thing Done In A Hurry has been cleaned up into general application code in mojopatch.c, platform stuff in platform_*, and UI stuff in the UI drivers. Over all, this was a lot of good cleanup that'll make sane Linux and Windows ports much easier.
