[immodule-qt] I have implemented QInputMethodEvent Property for the discussion

[Daisuke Kameda]

I have implemented QInputMethodEvent Property for the discussion.

The property contains ruby (Japanese hiragana), a language, underline's 
color, background color, etc., as before discussed by this mailing list. 
These are important for the advanced input system, and implemented 
by gtk+ about the color. 

Based on this implementation, let's discuss about the property.
