[Shindig-1085] stylesheets with different media attribute shouldn't be merged

Proposed fix for SHINDIG-1085 stylesheets with different media attribute shouldn't be merged.

Modify HTMLContentRewrtiter and the unit test file to concat the link tags based on media attribute.

Add some code cleanup for lines > 100

Proposed fix for [Shindig-1085] stylesheets with different media attribute
shouldn't be merged.

Concatenate stylesheet links for each media type instead of for all links.

Update the test file to test this scenario.

Review is greatly appreciated.

We need to check whether it includes style OR link as they are both handled by
this method.

Add check for "link" tag if its in the content rewrite include tags based on
review from Mat Mannion.
