- Profiles format defined by property pan.formats (fixed)
- Default directory for profiles defined to build/profiles (instead of build/xml)
- quattor.deploy.and.notify: process .xml, .xml.gz, .json; .json.gz instead of every file found in profiles directory
updateComponent: remove useless --core and --grid
