Subject: [PATCH] Added --skip-options to ignore certain xrandr options

See issue #26. This feature is required if tools like redshift interfere
with autorandr: Redshift e.g. continuously adjusts the --gamma values
such that autorandr never recognizes its configurations. This option
allows users to tell autorandr to ignore, and not fiddle with, --gamma.
