Issue #40: https://github.com/doctyper/flexie/issues/40

Contains fix for 'GET http://domain.com/data:text/css, 404 (Not Found)' error generated by Flexie. This is caused by the ADBlock plugin in Chrome; it inserts 'data:text/css' into the code, which Flexie sees and attempts to parse, resulting in an error. Fix simply tells the code to ignore 'data:text/css'.
