2016-02-15Revert "No need for usage()"Markus Teich
This reverts most of commit a6dc051e3744ce5b14c54d2d246d3e8258207e76 and fixes some related stuff: - keep spelling fixes from original commit - make -h and -v also work when followed by more arguments - any unknown flag prints usage - fix output of -v to display "slock: version 1.3" instead of "slock: slock-1.3"

There are 2 arguments why -v and -h are broken: 1) if you are running off git, -v will show the last stable release, effectively making this option useless. people running stable versions leave open an attack surface this way in case there are vulnerabilities found. 99% of the people are also using package managers to keep their software up to date, instead of running $TOOL -v to check how old it is. 2) -h is a sad excuse for not just looking at the manual page (man 1 slock). Given we accept a post_lock_command, we can't be as liberal and just intercept certain flags. I changed the manpage to reflect this change.
