[Toaster] Toaster documentation, 1.6 release

[Barros Pena, Belen]

Hi Scott,

As I mentioned, we would like to document how to set up a Toaster instance
in a remote host. Alex Damian sent an email to the mailing list explaining
the process back in February. This is it:

https://lists.yoctoproject.org/pipermail/toaster/2014-February/000464.html

We are thinking of documenting this in the wiki for the moment, with maybe
a link to it from the existing Toaster section in the Development Manual.

Just contact any of us, or the Toaster mailing list, if you have any
questions.

Thanks for your help with this!
