Groups for starred solutions

[maraf]

Add groups for starred solutions and add ordering of starred solutions according to groups. Currently when you have starred solutions across multiple projects, you get solutions mixed alphabetically across projects. This can be little confusing.

Maybe, adding multiple icons for starred items (not only pins, but use of various stars, like in GMail) can solve this issue. In configuration there could be definition for ordering (= importance) of different stars/pins.

Starred items should keep the order in which starring occurred.

Using Ctrl+Down and Ctrl+Up an user could jump through groups of starred items.

Consider adding management of pinned files to the configuration window.
