Add option to wait for patch analysis

[TimJentzsch]

Inspired by the poll, it would be cool to have an option to only be notified when the patch analysis is complete.
First, a simple delay should suffice, later we can expand by analyising the threads, looking for the Analysis Status: Done keyword.
Of course, for blog posts / updates without the Analysis Status segment the bot would notify the user immediately.

That would be great for the bot itself but I don't know how it would work for the channel. Perhaps the channel could be split in two.

I don't think that the delay makes any sense, there is no real reason to half-do this
