changed so command line arguments can be provided to configure the bar.

Provided extra command line arguments that can be supplied to configure the bar without having to re-compile it.
A little hacky but it seems to work well enough.

I don't really know how palette.pl works/haven't looked at it, so I am not sure if removing files from the .h breaks this temporarily.

I kept the original option characters so as not to be confusing, as a result some of the new flags aren't that intuitive though.
