[PATCH] Add support for Windows clipboard (WSL)

[Douglas Silva]

Ok, now we're using the snapd method for detecting WSL, and I've tested your suggested "paste_cmd".

## paste_cmd
One problem. The Get-Clipboard cmdlet works as expected when you execute it from the shell, but not when called by pass. After 45 seconds the clipboard will still contain the copied password, with one addition: an empty newline. I couldn't yet figure out why.

## copy_cmd
I also tried to replace the older "clip.exe" with the Set-Clipboard cmdlet, but it only broke the functionality (clipboard stays empty).

Am I using these Powershell cmdlets wrong?
