Image plugin warning icon and styling
prevent link popover from always wrapping

Decided to still let it wrap if close to the edge. That popover still
needs attention re: the icons, but it's better for now. The change to
the .coffee file was made to prevent extra spacing from getting
underlined, but I couldn't figure out a way to comment that section of
the file, so noting it here.
arrow was too big in others' computers

Dunno why arrow character is really small in my machine/OS/browser. This
still looks small on my machine, but is "good enough", and looks much
better on Tom's and probably Kathi's.

change default position of "description missing" message

For now, just always have it on the left so that it isn't "missing" on
big images.
move "thank you" msg styling from JS to CSS

The white background being set in JS was persisting even if one removed
the alt value.
use actual label instead of literal "this element"

- "Advanced options for this [element]" instead of "advanced options."
- "Copy [element]" instead of "Copy element"
I also removed some periods because they bugged me, but if somebody
really wants them, I won't fight it.

let semantic blocks scroll with content (Aloha-Editor half)

Requires a forthcoming change in github-bookeditor
Fix infinite recursion bug on tooltip/popover.

When the math popover is closed, it calls for the tooltip on the remove icon
to be destroyed. This causes a hide call on the tooltip, which causes a hidden
event on the icon, which propagates to the tooltip, triggering the entire
process again. By stopping this propagation, the error is avoided.
