Sam Ravnborg 98e5a1579e kconfig/lxdialog: refactor color support
Clean up and refactor color support. All color support are now
in util.c including color definitions.
In the process introduced a global variable named 'dlg' which is
used all over to set color - thats the reason why all files are changed.
