This commit renders the same CSS files using both the "less" and "scss"
CSS generation engines so that the results may be compared. This is a
comparison script:
old_main_css=$( grep -rl normalize.css _site/*.css )
new_main_css=_site/css/main.css
old_rtl_css=$( grep 'Language specific styles that override default' -rl _site/*.css )
new_rtl_css=_site/css/rtl.css
(
diff -ub $old_main_css $new_main_css
diff -ub $old_rtl_css $new_rtl_css
)
CSS file names are now updated when visitor's browser must reload them
Allow files with .css extension to skip less compilation (IE6 invalid CSS syntax)
