Tweaked Pipeline generation/execution.

Execution works but doesnt update page yet, nor poll status.

team3DB.sql -- changed beginning services to have port 5080 instead of 5181.
QueryManager.php -- fixed get query to use new formatURI and typeURI
Query.php -- allow constructor without typeURI or formatURI
User.php -- simple wrapper for user objects
UserManager.php -- created get by email to get User objects.
SelectPipelines.php -- rewrote some loops and set it to dynamically get user id, and pipeline id when building table
pipeexecution.js -- javascript code to start pipeline execution
execute.php -- send a pipeline to be executed to viskobackend (from pipeexecution.js)
