Creation of Jenkins build variable HP_RUN_ID that contains the id of the run from PCALM.

As before, I've required the RunID for later steps in my build process, so I've changed this class to output the RunId to a variable.

This means in later steps, I can use ${HP_RUN_ID} to get the Run ID.

We're also now on the development branch and using CRLF as requested :)
