Enable pitch and roll widgets in Collect, to supplement compass bearings

What tool are you using?
ODK Collect 1045 (Device LG G2)

What is frustrating, troubling, annoying or lacking?

A new widget to record compass bearings was added to ODK collect in Oct 2013.
See:

From the above commit, the values for pitch and roll are also read from the 
device's sensors (however these 2 values are //commented out in 
BearingActivity.java)

How would you like it to work?

Similar to the new 'bearing' widget, to have 2 new widgets for "pitch" and 
"roll  "bearing" of type decimal, appearance="pitch" and "roll" which use
the device's g sensor to get readings of the orientation of the device.
