We always intended to move the pointer up when you were at the
top of the viewport and scrolling up, and we always intended to
move the pointer down when you were at the bottom of the viewport
and scrolling down. We didn't intend to move the pointer up
when you were at the bottom, or vice versa. This commit fixes
that bug, simplifies the code, and inlines the code into ui.js.

This is a bit wasteful on most systems, but will result in their
looking pretty sharp on Retina displays.
(I also go and actually fix up the size we request for a bunch of
these so that they actually match the size of the gravatar in the
document -- previously we were requesting a size 30 gravatar when we
were displaying it in a size 25 space, which leads to unnecessary
ugliness upon resize.)

Code prior to this commit was functionally working, but semantically
flawed — returning false does not short-circuit _.each like it does with
$.each. It now uses _.every, as suggested by Steve.
In addition I renamed the function to be more descriptive, added a
comment, and eliminated needless double negation.

In a few cases the $.each was doing something imperatively that was
terser and easier to understand by using a different Underscore method,
so a few of these I rewrote.
Some code was using the fact that jQuery sets `this` in the callback to
be the item; I rewrote those to use an explicit parameter.
Some code was using $(some selector).each(callback). I converted these
to _.each($(some selector), callback).
One function, ui.process_condensing, was written to be a jQuery $.each
callback despite being in a totally different module from code using it.
I noticed this and updated the function's args.
