Making sure edit button for baseline deactivates when we move stages
Renamed ImportService servlet to ShapefileImportService to be more descriptive and because I will also be writing an ImportService to import session files. Updated import service url to be specific to shapefiles

Added an export service (ripped from watersmart) - we really need to start modularizing these things
UI export function complete and tested - did not put any function accessor in the UI yet since we haven't agreed how that should be implemented. Button? Where?
