Add to whitelist/blacklist links from mail view

[mbautista]

Hello,

Thank you for these great plugins, they really are awesome !

This is not an issue but e feature request : it would be great to have "whitelist this sender" and "blacklist this sender" links available in the mail view. That would avoid copying the email address, then going to Parameters > Account > Whitelist > Add to whitelist, Pasting the address and submit.

I'll try to implement this and make a pull request as soon as I can.

Thank you.
