This allows for source code generation. Packages in <application>/app folder are scanned manually as opposed to the `packages.Load` scan which will fast fail on compile error, and leave you with go files with no syntax.
Added a check to see if harness had already started, saves a recompile on load
Added check to source info for local import renames
Removed the go/build check for path and just check existence of the path
Formatting updates
Added packagepathmap to the SourceInfo, this in turn allows the RevelCLI app command to pass the source paths directly to Revel directly
Added default to build to be "target" of the current folder
Renamed source processor
