tine 2.0 email client

I have been working on the tine 2.0 email client for the last few days and I am making fast progress.

The new Felamimail IMAP client is at the moment able to fetch and cache mails and folders, get the message contents and show the mail flags (unread -> bold row, answered -> icon, forwarded -> icon, flagged -> row in red font color).

As next steps I am going to implement the 'write new mail' and 'reply'/'forward' functions and the handling of file attachments.

Lars is working on the ActiveSync support for emails. When this is finished, we are able to push emails to mobile clients!
