After Logging into run keeper we need to get Runkeeper ID

ID is not email, which I now believe we do not have access to, however
it is unique so we can use it to store users mileage for WNC.

This commit also includes adding runkeeper id as a workout parameter.
Inserting/updating to WNC database from android application

2 different workout variables one for runkeeper, and the other just for
when within WNC. Had to change when workout application variables were
initialized so that parameters would not be null. Added a new calss for
communication with the database, as well as included the php file for
inserting/updating users mileage.
