Colors are configured through the command line so that swaylock conforms to the i3lock fork 'github.com/chrjguill/i3lock-color'. Differences from it are that one letter options '-r' and '-s' are not implimentend because '-s' is already used by '--scaling' in swaylock. This commit also fixed whitespace in 'include/swaylock/swaylock.h' and changed `parse_color` in 'common/util.h' so that it can accept colors that do not start with a hash. This was done to keep compatability with the i3lock fork.
