Selection options

[szaimen]

Please add these ribbon options for selection:

• Select all
• Select none
• Invert selection

Would be really helpful especially for touch input.

This is how it is currently implemented in the file explorer:

Select all, and clear all are already options. Since the idea is straightforward I will go ahead and approve this issue.

I just don't know, if these option are fitting well in the "Layout" category. But that is a discussion for another time.
