Theory "alternates" support
* This is a feature that Dejan and I want for the upcoming tutorial.
It allows rapid prototyping of new decision procedure implementations
(which we may choose to demonstrate), and a new --use-theory command-line
option to select from different available implementations. It has no
affect on the current set of theories, as no "alternates" are defined.
* Also update the new-theory script, which was broken and incomplete.
