Make Grid Column Option a small text number field.
Rework some of the globalizing of deprecated JS vars.  I don't like everything we're deprecating there, nor do I like calling it wpsc_ajax.  We should not be deprecating our AJAX vars, and our global deprecated variables should be kept and named separately.  This commit temporarily fixes the fact that the globalization was not actually working, thereby breaking things like Thickbox.  See #1110.
