Minor jshint changes to wp-e-commerce.js.  This it taking an Advil for an amputation, but hey, it's better than nothing.
Have better handling in WPSC_Claimed_Stock for passing IDs and objects.
Assign WPSC_Countries to variable in static singleton check.
Minor doc and whitespace fixes.
Check proper variables in WPSC_Visitor.  Not sure how this class ever properly functioned, given the amount of improperly referenced variables.  Magic?  Review: @JeffPyeBrook
Modify wpec_taxes class to always expect  to be an array, and properly internationalize string.
