Adding an endpoint and authentication

[aniketdharia]

When we create a course there should be an option to add an endpoint and authentication information using which the course will pass the xAPI information to the LRS providing the end point.

There may be a better way, but I've been adding ?agent={"mbox":"mailto:name@domain.com"}&endpoint=https://domain.com/data/xAPI&auth=Basic xxxxxxxxxx to the query string.

This is implemented now in the develop branch.
