Minor updates to command line and GUI help following the introduction of processing for single files from the command line in 'no profile' mode.
Further changes required since the PRONOM web service location has changed following a major update to the TNA web infrastructure.  This meant there was now a test failure as it was hard coded to look in the oold location, and at the same time I took the opportunity to update to the new location in the default settings.
Miscellaneous changes relating to the use of up to date signature files, and the recent change of the PRONOM  web service to apps~ from www~ as part of the general TNA website reorganisation
Reverted parent pom to not fail on warnings
Restored signature files that had gone AWOL in Git
