Whole tonne of changes/additions!

+ Fix crappy bottom of UI appearance on iPhone5/5C/5S.
+ Added a new first step of the robot activity: it will orient the robot to 0 degrees based on the phone's orientation (beginnings of experimenting with something approaching the ability to discover its environment perhaps).  Once it's done orienting the usual old stuff will commence.
+ Adjusted down the loudspeaker volume (so it doesn't sound horrifically distorted with the RoboMe's bad DAC/speaker).
+ Cleaned up a crap ton of old noisy NSLog stuff in my own code (there's still a lot from RoboMe SDK I can't do anything about sadly).
+ Cleaned out old disused UI elements (and related event functions) from the code.
+ Added full-head-tilt-up to the app start up procedure (useful when RoboMe exoskel is on your desk with your desktop and you need to read the cradled device's display). :-)
+ Disabled some old TTS/battery related functions that weren't really used anymore.
+ Improve information regarding exoskeleton battery level (textual).
+ Remove the Flite/SLT stuff (maybe it will help improve startup times, just maybe).
+ Add web-based logging (easier than always having to follow the damn thing around with an attached dock/Lightning cable) -- disabled by default, script available later -- or you should be able to roll your own with one line of PHP. ;-)
+ Cleaned up a few compiler warnings (I think I did this anyway).
