fix(demo,codepen): use escaped html and special for demos

Codepen is expecting escaped html, it is far too difficult to walk the dom and replace only certain dashes.
escape ampersands in escaped quotes - 5/12/2015 release of codepen API introduced an undocumented breaking change
replace accent char - changes to codepen api causes this demo to break.  Replacing with quote instead of accent.
replace special character- undocumented changes to codepen cause this demo to break when editing in codepen.

Closes angular#2833.
