Ability to close all background apps

[jsalatas]

This comes from a google play review.

It does the job nicely but would be great with an option to close all background apps with the same tap.

I didn't though of this, but now that you mention it, most of the times I'm closing all apps before turning of the screen. I might also create an exception list, for application that you may not want to loose it's state, like for example google maps. I guess I don't want this to be closed in the middle of my route :)

Thanks again to the user who reported it. :)
