[jitsi-users] Add taskbar for windows (and other OSes) for master password dialog



When starting jitsi with a master password, the master password dialog
shows. A Windows taskbar is not created for this dialog however, so it can
be easy to lose this behind other windows on the operating system. I would
like to file an issue to add a taskbar icon when the program is started and
waiting for the master password.

I would also suggest a patch for this, using the following stack overflow
question as a suggested fix: http://stackoverflow.com/a/25533860.
