getAttributeOnSelection function
some nice css to that reflect when a button is active
handle logic for line lengths with 0
ends of line shouldn't show incorrect formatted status
remove post ace event
remove white space
dont assume formatting is on the start of any line
Merge branch 'afterEditHook' of github.com:ether/etherpad-lite into getAttributeOnSelection
resolve issue where first char showed all formatting
docs but not sure how to specify the verison this was introduced
Merge pull request #2013 from ether/getAttributeOnSelection
