Sean Dague 537532931d Make changes such that -o nounset runs
This makes a bunch of variable cleanups that will let -o nounset
function, for the time being we hide nounset behind another setting
variable so that it's not on by default.

Because this is bash, and things are only executed on demand, this
probably only works in the config it was run in. Expect cleaning up
all the paths to be something that takes quite a while.

This also includes a new set of unit tests around the trueorfalse
function, because my change in how it worked, didn't. Tests are good
m'kay.
