New Collections Plus plugin

Just released a new plugin: Collections Plus.

Besides adding to the Admin browsing interface some of the features already available for Items (like a quick-filter and details about the single Collection), this plugin allows to customize the way single Collections appear, including Items sorting order, paging and theme. It also allows to customize the Collections sorting order.

Parts of this plugin were inspired by the Enhanced Collections plugin created in 2013 by the team of Bowling Green State University Libraries and by the Default Sort plugin created in 2014 by anuragji.

As usual comments and suggestions are more than welcome; many thanks to @chazzo for beta testing the plugin.
