UI bugs and improvements

- don't trigger glossary modal in edit mode
- remove show/hide animation on glossary modal
- rename Execute button 'Go'
- Typing enter on bundle should go to new window, not open in existing window
- Type enter /click on bundle in record/image/contents/html mode should show bundle
- Need hot key ('F') to toggle raw editing mode (changed from E)
- If in raw editing mode, type ctrl-enter save and switch out of it
- Change key bindings to mimic vi: i -> O, A -> o, 'd' => 'f' (for remove)
- Turn off scrolling on click
