Ported text command over to the new args classes
* Involved a big rewrite of arg_loader to accomodate nil and false better. Sadly this meant dumping ||= for if-statements. Blech, but works. * Updates to regression tests are pretty trivial. * Removed graphics_text_spec because, even though it looks useful, with rake sanity it really isn't. * Exposed font on deck as well Cleaned up graphics/text.rb too!
