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.

This commit temporarily fixes the fact that the globalization was not actually working, thereby breaking things like Thickbox.  See #1110.

If taxes are not enabled, don't show settings in metabox.  Note: if someone enables taxes, sets a price here, then disables taxes, and updates the product, and then re-enables taxes - the meta data for the taxes will be gone.  Super edge case, but worth noting nonetheless.
Incorrect method usage.
