Message:

Ability to set exposure arbitrarily (like "zctl set exposure")

A zephyr variable 'exposure' has been added.  It defaults to the value
in ~/.zephyr.vars, if there is one, or to realm-visible.  Setting this
variable does not affect the value in ~/.zephyr.vars.

Additionally, OWLVAR_STRING_FULL has been modified to allow custom
setting of validset.

This fixes ticket # 65.
