Patch from tsbere for new tab versus current tab behavior with the button bar:
---
The attached patch to trunk adds the ability to set an open-ils.toolbar.defaultnewtab preference to cause the toolbar buttons to open in a new tab instead of the current tab. Holding the "accel" key (default of ctrl on windows/linux and command on mac) will do the opposite.

I only applied this to the five commands currently in use on the toolbar for now. Any other commands added to the toolbar will need to have their command handlers in menu.js updated.
