new FetchSourcesFromManifests class (JBIDE-16632)
check if Eclipse-SourceReferences exists in MANIFEST.MF and log WARNING (JBIDE-16632)
clean up comments/formatting and implement digest file ALL_REVISIONS.txt (JBIDE-16632)
JBIDE-16632 relative paths are bad; ensure everything is anchored below project.getBasedir()
fix copyrights (2014)
fix relative path for MANIFEST.MF file; turn com.googlecode.ConsoleDownloadMonitor back on; reformat source
ensure this.outputFolder/all exists; use temp files instead of reusing the same file (in case of stale NFS handles) (JBIDE-16632)
fix copyrights, remove deprecation warnings for expression="$\{foo\}" -> change to property="foo", and add usage code to README for new fetch-sources-from-manifests mojo
JBIDE-16632 fix bugs: qualifier not calculated correctly; old component source zips should be purged before overall source zip is created
JBIDE-16632 don't delete MD5 files if they already exist; don't write to them again if they already exist
disable com.googlecode.ConsoleDownloadMonitor and just dump resulting file size into log; DownloadMonitor produces a lot of garbage in Jenkins log
