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.
Some projects do register COM server in Debug/Release sonfigurations.
We should do it with per-user redirection so that there is no need to
run elevated Visual Studio.
This has no effect on COM server registering in installed Opne-Shell.
It is related only to local development.
