ofxui+ofxXmlSettings don't store the values of ofxUIDropDownList correctly.

Merge branch 'master' into v0.21 (strategy=ours)
ignoring a few commits in master (the experimental measurement scaling)

v0.21 summary:
upgrade to openFrameworks 0.8.4, Xcode 6.1 project files.

several GUI related changes:
* GUI related code now resides in a separate file. If it doesn't stop growing it might make sense to encapsulate it.
* ofxUIDropDownList is now used as a "disclosure menu" to avoid the buggy click-through behavior.
* ofxui and ofxXmlSettings didn't save the state of the drop down menus correctly. We are now using cjson instead. Might need some refactoring.
* Serial START/STOP/CALIBRATE button behavior and app states have been changed (hopefully less confusing now)
