Adding test for content negotiation
Adding email/pw auth to sparql query page
Line ending for example file.
This adds content negotiation test and simplifies the use of vivo as a
sparql endpoint.

Modify the servlet at auth/sparqlquery to accept the additional parameters:
email - email/username of a vivo login account
password - the clear text password for the account associated with the
email
