Add project list to sidebar

[smbkr]

Extensions are able to add custom sidebar items. It would be useful to have an option in this extension, to add a sidebar item that lists all projects, and allows the user to switch the current workspace to a different project by double clicking the project name. Shortcuts could be added in the header for common actions like refresh project list.

Hi @smbkr, I've been thinking about this lately, and I'm planning to do it soon, but as an enabler to this feature, I'm working on a big change that will not search actively for repositories, but use chokidar to keep repolist always refreshed.

As soon as I finish this base changes, I will sure get this issue implemented.

And if you feel comfortable, It would be great to receive some PR around this because maybe we can finish both implementations in paralel ;)
