* Adding Set Width (horiz-adv-x attribute) slider to the SVGFonts dialog.
* Fixed the order of some language options at the i18n preferences page.
* Fixed parsing and handling of u1 and u2 (CSS2 unicode range) attributes for kerning pair nodes
* Fixed a warning in helper-fns.h 
* commented out unused variable in sp-font.cpp
* refactoring of nr-svgfonts.cpp
* using 1000 instead of horiz-adv-x when scaling the glyph coordinates. Probably should use a value based on units-per-em in the future. Or maybe accent-height, 
cap-height, x-height... I don't know. I should study this subject a bit more first.
