Close picker on scroll.

The picker doesn't close on scroll with my touchpad in Chrome, so I've extended the list of events to be watched. Apologies for lack of a complete patch, I don't have npm to get grunt and create a minified version.
Fixed Bootstrap sprite. Fixes #65.
Merge branch 'patch-1' of https://github.com/hotwoofy/jquery-timepicker into hotwoofy-patch-1
Set close handler to unattach itself to avoid repeat firing when scrolling. Namespaced events.
