Now shows guttermarks

Browse Source 
Takes new params for markOn, markOff and initMarks
Creates new span DOM elems for markOn and markOff
Determin if a line is foldable by there being a range with chars in
between (ie, start & end line's & ch's not the same)
If it's foldable and we're clearing or setting up the initMarks, show
markOff marker, otherwise markOn marker (as cloned nodes)
Also set to the markOff marker when clicking the inline widget
