IMAP server information

There are a large variety of different IMAP servers in use and while they all meet the basic requirements in RFC 3501 there are a lot of optional features that can greatly affect the resulting capabilities.

The two key things we are looking at now are the result of a capabilities request and the permanent flags report from a select (if it lists \* then we can setup our own flags).

The servers we have information about are
