Upgraded ChibiOS to 2.6.1 to fix some HAL bugs kicking around
So far, the only problem is a hardfault in FlogFS mounting now
That will be dealt with later, in a session dedicated to fixing FlogFS
Updating to patched FlogFS
Added safety against multiple initializations in MT29xx
Added 'back' button support in UI
Holy crap --  a lot, but it's all intertwined and so is lumped together
-Datasources now name the types required for more-easily defined listeners
-Fractional types introduced; hopefully let sensors use those soon
-An awesome logger GUI tool now exists, supporting fairly arbitrary datatypes
-There's a pressure sensors
-The sensor display utility is much more robust (if that matters)
-Fixed a bug in the LED GPIO configurations
-Increased stack size for UI thread
Updated to flogfs with a stupid fix
