Access to master password protected resources

[sid77]

Similar to issue #22 , Convergence needs access to master password protected resources when providing certificates to the user so the master password dialog should be presented in case the db has been closed. Unlike issues #22 and #62 I wasn't able to pin down the exact location where the privileges are needed. From the console output:

ShuffleWorker accepted connection: 0x... Spawning connectionworker... Posted message to ConnectionWorker!

and nothing more: as you can see, it looks like serialized information cannot be accessed. I tried to reopen the master password db using the same code supplied in pull request #64 with no luck :-/

Temporary workarounds:

1. disable any extension which close the master password db (like Master Password Timeout)
2. reload an HTTP page/open the db from preferences in order to refresh credentials

I'm still baffled as to why it requires the master password at all. It's not saving any passwords after all, or do all the certificates get saved securely through this?

Edit: Nevermind, I just saw #64 It's a bit annoying to get asked for the Master password so early, but it's livable.
