Update ibus-anthy to 1.2.7.

    Released 1.2.7

    Added --with-layout option in configure for IBusEngineDesc.
    Added symbol and hotkeys property in IBusEngineDesc.

    Added --with-layout option in configure for IBusEngineDesc.

    New ibus 1.5 will use the IBusEngineDesc.layout but Japanese input method
    inherits the system keyboard layout so I added the configuration.
    Probably ibus-anthy would need IBusEngineDesc.layout = 'default'.

    Added symbol and hotkeys property in IBusEngineDesc.

    Fixed UTF-8 copyright on about dialog.

    Fixed undefined getuid in engine.py
