Finer-grained controls on menubar; .text-container class replaces kludgy 'p,h1,h2...' list.
"None" display style works; hides all annotation-y things entirely.
Annotation enable/disable switch works in UI (doesn't  do anything, though)
Annotation enable/disable switch actually turns on/off ability to annotate.
Small scrollbar bugfix on last commit.
dual menubars at top-right of screen both work: show/hide annotation, also annotation style.
long annotations get gradient on their right
snippets can be up to three lines long.

horizontal gradient showing their end.
