Adding bidi-isolation to reference numbers

This is a quick-fix to support proper rendering of <sup>[1]</sup> elements
when the sentence contains a right-to-left word.
Amended: Changed from working through jQuery 'wrap' to CSS unicode-bidi.
Amended: Dos2Unix conversion to get rid of pesky hidden characters, also
corrected all of Amire80's comments.
Bug: 36032
