Allow "Team > Pull" on working sets with closed/non-git projects

[sebthom]

Description

The context menu entry "Team > Pull" should be enabled for working sets that contain closed or non-git projects next to git projects. The pull action should then only be executed on the open git projects.

Motivation

Being able to git pull multiple projects at the same time is a great time saver, especially when used via the working set entry in the package explorer. However not all working sets contain only git projects or for performance reasons not all projects are open. In these cases one has to manually select all the git projects separately to update them.
