alarm/fake-hwclock: use systemd timer unit, to 0.3
* PKGBUILD: modified to install directories with correct permissions (in case of a restrictive umask). * PKGBUILD: change arch to any as this is arch-indep. * fake-hwclock.sh: add 'load' command that sets the system time only if the current time is older; make 'set' an deprecated alias of it. * Add fake-hwclock-save timer and service that saves the time every 15 minutes. * install: suggest to enable timer unit instead of cron.
