Swap dollar ($) and backquote (`).

The goal is to get the key above tab switch between windows of
an application when pressed with the command key.
Swap semi-colon (;) and colon (:).

With languages like Clojure, I often want to "keep my flow" going
when typing a colon, whereas I type semicolons less frequently
and/or they're normally the result of deliberate decisions (e.g.,
"I'll add a comment here to explain...")
Switch locations of the '/" key and :/; key.

I forget what instigated this change, but I'm used to it now and
it feels nice.
