should this implement It2MeConfirmationDialog?

[dcaiafa, 2014/12/20 00:22:00]

Done.

don't need this to be ref-counted. Use DeleteSoon() to delete the Core on the UI
thread and the proxy is deleted and a weak_ptr to post tasks from core to the
proxy.

[Sergey Ulanov, 2014/12/19 03:16:19]

this can be moved to the .cc file.

[dcaiafa, 2014/12/20 00:22:00]

Done.
