Use style sheet, remove URL rewriting

[jonathantneal]

This PR changes how <style> and <link rel="stylesheet" /> stylesheets are updated in IE11. Instead of rewriting <link rel="stylesheet" /> tags as <style> tags, the CSSOM StyleSheet text is rewritten.

Benefits

• Uses cssText instead of createElement and innerHTML, reducing the number of DOM modifications.
• Preserves linked stylesheet href, removing the need to rewrite internal URLs.
• Reduces the overall script size and code complexity.

Be sure to test this branch before a release. We are probably testing with different sets of data. If it works for both of us, then 👍 👍 .
