Start refactoring handling of color....
Start refactoring handling of color. This is one more step into getting rid of the old way of handling colors in IPython, in particular here we move the scheme/style as a configuration option of the parser instead of passing it around into the formats functions. Also remove our own usage of deprecated arguments.
