WIP: Mapshed Geoprocessing Tools

This PR aims to:

Add a new module to support MapShed functions
Collect common functions into a utility module
Offer a means to show how both (TR-55 and MapShed) modules can be deployed and accessed simultaneously

Initially I am copying over everything from the SummaryJob module, but will refactor and simplify considerably before merging.

This effort is ongoing.

Some initial results:

vagrant@worker:/opt/app$curl --silent --data "" 'http://localhost:8090/contexts/geoprocessing-context'
OK

vagrant@worker:/opt/app$ curl --silent --data-binary @request.json 'http://localhost:8090/jobs?sync=true&context=geoprocessing-context&appName=geoprocessing-0.4.0&classPath=org.wikiwatershed.mmw.geoprocessing.MapshedJob'
