Remove rendering whitespace, issue 12

The profile_handler js file had a unicode character, U+FEFF, which is ZERO
WIDTH NO-BREAK SPACE. It represents UTF-16 and not UTF-8. This unicode
character is depracated and causes the issues seen where there is annoying
whitespace above the script when it is appended to the body by
Rack::Response.
