Toggle align/collapse with mutliple calls

[sgrove]

I'm working in a codebase that isn't using aligned let-bindings, etc., so I often find myself absentmindedly hitting the key-chords to align it while I ready through the code. Afterwards though, I have to undo, or if I forgot and started editing the body already, I have to manually (via some emacs macro) go through and collapse all the whitespace together.

I'd love if I could run align-cljlet once to align everything, and twice to collapse everything.
