Alternative LPR Backend

Hi Daid,

Would you mind looking at some patches I have been working on. I have been using an alternative backend to the existing serial comms in Cura.

This backend uses the LPR protocol to send jobs to a 3D print server, namely matterQ (http://matterq.org).

Are alternative backends something you have considered having in Cura? I have implemented lprWindow separate from printWindow as they both do very different things and it makes maintenance easier (whether you decide to merge this into the mainline or whether I maintain a separate branch).

If you get a chance to look I would love to hear your thoughts.

Ta,
Stefan
