This was an attempt to avoid opening up a whole status line in the
bottom of the window much of the time. But it doesn't really work
since as soon as you have a syntax error (which are relatively common)
you get that whole line opened up. That it, this attempted GUI interaction
depended on the bogus premise that read errors are somehow happening
in a transient way between error-free states.

running the 'redraw the definitions/interactions label' timer when the
language didn't ask for those labels; this commit also avoids running
the timer when the user has disabled the labels
so that it waits until online check syntax actually
finishes (otherwise, there actually is a leak;
the link is broken when the message comes back from the
other place)
then hide the definitions/interactions labels for a while (2
seconds currently). also, when the 2 seconds expires, fade back
in instead of just appearing immediately
This fixes a bunch of little things, including switch tabs between
windows with different states (closing PR 12341) and switching to
a non-module language.
I believe that this can go wrong in the case that you edit a buffer and switch tabs
before drracket fully finishes responding to the edited buffer (due to a queue-callback
that postpones some of the response to editing the buffer) for online expansion.
At least, this is how I guess that the error below happened:
send: target is not an object: #f for method: get-view

this also gets rid of the module-level imports as annotations in the bar
along the buttom of a drracket window, which eliminates the use of the
'drracket:check-syntax:mouse-over status line and thus:
