start/stop scripts for tracking apache server on VM plus an apache configuration file
wtsi-local folder is deployed by the build script
test simplified to ensure date diffs are computed correctly

stop and start are now softlinks created during webinstall, do not try to chmod them in blib
added parts of Changes and MANIFEST which went missing in commit 1dfcf0948e
