IMAP library

[Laeeth Isharc via Digitalmars-d-learn]

Started working on a simple one.  It's not exactly rocket 
science, but a bit fiddly. Need to have some way of manipulating 
email in D though.

Is async important (so you can pipeline commands) and also 
multiple threads ?  Or is a simple enough version useful as a 
start?  If async (ie pipelining and registering callbacks to 
watch state) is important, is it okay to use vibed?  Or better 
not have the dependency.

The other aspect is mime.  Have ported headers for GMime but 
still nee to write the high level wrappers.
