Custom Script path location

This is similar to Issue #104. We have a team that has a globally shared folder on box with our custom scripts. I made a toolbar to share with everyone but when they press any of the buttons it cannot find the file because it is looking at the path that was saved from my computer. FT-toolbar I believe solved this through ~/box/etc/etc instead of saving the full path from c:/user/box etc etc.

This is preventing our team from switching to kbar.
