Improved Internationalization and Localization

==============================================

Commiting GSoC project by Xiangquan Xiao trunk.

Applied as separated patch, because svn merge produces to much false
conflicts and worked really slow.

Details for usage would be published on code.blender.org soon.

Thanks to Xiao for implementation of project, Campbell to code review,
Dalai and Gez for pointing to nice font and everybody else who took
part in improving i18n support.
