Log Message:
Update to 1.2.1. From the changelog:

- The 'isync' compatibility wrapper is now deprecated.
- An IMAP Path/NAMESPACE rooted in INBOX won't be handled specially any more.
  This means that some Patterns may need adjustment.
- The default output is a lot less verbose now.
  The meanings of the -V and -D options changed significantly.
- The SSL/TLS configuration has been re-designed.
  SSL is now explicitly enabled or disabled - "use SSL if available" \ 
is gone.
  Notice: Tunnels are assumed to be secure and thus default to no SSL.
- Support for SASL (flexible authentication) has been added.
- Support for Windows file systems has been added.
- Support for compressed data transfer has been added.
- Folder deletions can be propagated now.
