Enable title and msg text alignment for materialDialog

[edwardcahyadi]

For my own project, I added titleAlign and msgAlign named argument to materialDialog because I was using msg that would span more than one line.

This may be helpful for others too.

--I think we should replace both msg & title variables with a widget next time to give the user the fill control
