[BZ#779611] avoid horizontal scrolling in the notes popover
Submitted by Matthias Clasen
Link to original bug (#779611)
Description
We generally avoid horizontal scrolling where we can, and instead let lines wrap. This was overlooked in the notes popup.
The changes to make here are
a) set hscrollbar-policy to never
b) make sure that the textview wraps properly. if not, figure out what changes are needed
