Add the best hinting configuration for Noto Sans CJK to use in fontconfig

[GoogleCodeExporter]

Noto Sans CJK requires FreeType 2.5.x  to utilize Adobe's CFF rasterizer that 
was added to FreeType 2.5.x.   Moreover, fontconfig has to be configured to use 
the full native hint and gray-scale rendering (as opposed to autohint and 
subpixel rendering). 

We have to document this somewhere (FAQ, release note, web page, etc)  so that 
both individual users and distribution builders can configure fontconfig 
properly to get the best result. 

Making our own deb or rpm package is another way to achieve this.
