Use more convenient format for color settings

We are storing color settings in BBGGRR format (for historical reasons).
This may be confusing for people that are used to (more widely used) RRGGBB format.

Thus we will present color settings in RRGGBB format when editing.

We will still use BBGGRR format for those settings internally. To
maintain backward compatibility with existing settings stored in
registry/xml.

Also setting descriptions now contain hint about expected color format.
This way it should be more clear what values `Open-Shell` expects.

Fixes #82, #1141.
