Connection time out

By popular demand, it is now possible to handle time out during connection to IMAP, POP3 and SMTP servers.

There is nothing to change in your code to enjoy this new feature, at least if you already set a time out handler on the store (vmime::net::store::setTimeoutHandler). The same time out handler is used for connection and for data exchange after the connection has been opened.

Please note: for now, this is only available in VMime SVN, revision 559, and for POSIX platforms (this feature is not yet supported on Windows).
