Restoring seamonkey

[Mikhail T.]

Hello!

I'm dressing up a fairly low-powered machine, and having both browser 
and e-mail client in one process would be useful.

The port-deleting commit cited poor update frequency, but the upstream 
<http://www.seamonkey-project.org/> is now at version 2.53.1 -- which 
means, they've made several releases in last July, when the port was 
removed.

Maybe, it can be brought back? Thanks! Yours,
