Clarify in tooltip what flag button does

[seanh]

The flag button on an annotation has a tooltip that says simply "Flag"
(or "Annotation has been flagged" if it's already flagged) but there's
no indication to the user what flagging is or does (even when they click
the button, all that happens is the flag turns red):

(or, err, blue?? not sure what happened in this screenshot)

"Flagging" can certainly be misinterpreted. I think some apps use it as
a way to keep track of "special" or "favorite" items (usually called
"starring" in most modern apps), or have a variety of different "flags"
that you can apply to an email or whatever it is (important, work,
personal, etc, this is usually called "tagging" or "labelling" in most
modern apps).

This commit changes the tooltips to clarify that what the button does is
report the annotation to the moderators. I've used the verb "report"
rather than "flag" as I think "Report this annotation to the moderators"
sounds better than "Flag this annotation to the moderators". Either way
I think "to the moderators" is important to clarify that this button
sends a message to the moderators and isn't, for example, just flagging
for personal use like starring / tagging / labeling.

I like the use of “Report” rather than “Flag”: I agree it’s less prone to confusion, and it seems to be more widely used elsewhere:

I wonder, since we’re already saying “report” instead of “flag”, do we need the “to the moderators” part, or can we leave it implicit that the report will go to (or has gone to) someone relevant?

I'm not sure. I think the presence of both "report" and "moderators" makes it doubly clear that what's going on here is reporting inappropriate content (as opposed to, say, reporting an annotation that has a bug). But maybe it's not necessary.
