Paste from wl-clipboard

[t1gu1]

Is your feature request related to a problem? Please describe.
If i take a screenshoot or copy a file from a client application, i can't paste the file/image i have in the wl-clipboard.

Describe the solution you'd like
Add a command that can paste from a wl-copy by using wl-paste.
wl-paste > clipboard.png

i could be nice that this is the same shortcut that paste.
So it will try wl-paste if nothings has been copied before and ask for a file name.

Describe alternatives you've considered
For the moment I open the terminal directly and I paste my things with wl-paste ? myFileName.ext command.
