Release 1.2.1: added upload stream rate limiting selections and more intelligent file selector dialog (that remembers your last upload).
Support for SerialUI 1.11's GUI termination command (now you can force the GUI to exit from the Arduino).
Adjusted size for MSW platform, and now seeding pseudo-RNG.
Minor mod to lower top label and make MSW version a bit nicer.
Added version info, version string to config.  Also moved some URLs here.
Added a (remote) check for available updates--both manual and, periodically, automatic/background.  Simply reads the version number in a file on the flyingcarsandstuff.com system and compares with internal version, notifying user of possible updates.

Also cleaned up the bitmap logo under MSW, by moving it out of the button and displaying a simple static bitmap.
Updated version/date in help string.
Minor mods to makefiles used to build.
