Comment 10 for bug 1743611

Branch for testing: https://git.evergreen-ils.org/?p=working/Evergreen.git;a=shortlog;h=refs/heads/user/dbriem/lp1743611_circ_history_by_year

Adds an info button next to Total Circs in the AngularJS staff client Item Status screen. Clicking the button displays a popover list of total circs by year.

I went with a click action instead of hovering for usability reasons, for example staff may want to copy and paste the popover info. The button is also tab accessible and formatted the same as the other icon buttons in the Item Status interface.
