Filter on 'Available Tags for Page'-popup stopped working

[joepmath]

After installing the SNS extension the filter/search-box in the 'Available Tags
for Page'-popup doesn't work anymore.

This is caused by a javascript-error. Below my small fix:

$ diff lib/sns/page_tags.rb.old lib/sns/page_tags.rb
 45c45
 <     Your #{current_tag[:name]}'s content here...
 ---
 >   //  Your #{current_tag[:name]}'s content here...

It's because the doc is improperly formatted. The < and > characters aren't being escaped when parsed.

There are reasons I dislike markdown. code and pre tags are handled differently, and can jack up the text around them. Move those tag pairs to their own lines, and change the indenting to the same level.
