* Created Storage->record_md5sums() and Storage->check_md5sums for use in daemons. These will record the md5sums of the program itself, all perl modules and the words file. When check_md5sums is called, it returns '1' if any sums have changed, which daemons can trigger on to exit (and systemd will restart them). Removed the basic md5sum check from anvil-daemon and switched to this. * Fixed how 'fatalstobrowsers' is invoked so that it only applies to programs running in a browser.
