Restructured packages
Tidied imports
Added class for writing/checking sync marker file in source/destination directory
Renamed SyncTask to FileSyncTask
Made FileSyncTask sync entire source directory when no includes/excludes specified.
Removed superfluous interfaces
Added pauses in tests which rely on marker writing being done at different times
Changed settings.properties to ApplicationSettings.properties (because that's what everyone at Bright is used to)
Prefixed all existing file sync settings names with fileSync
Added project README
