Feature: Roundcube Webmail Button to Delete all Spam

[X-Xadro]

Greetings,

Love your service so far and just have a little nitpicky thing that i would like to have added and that is a button to remove all mesages from the Spam/Junk folder.

I'm only asking because i have one on my old webmail that also uses Roundcube.

Would be great if it could be added, if not well its just 3 extra clicks.

Cheers!
