Color support for "git-add -i"
This is mostly lifted from earlier series by Dan Zwell, but updated to use "git config --get-color" and "git config --get-colorbool" to make it simpler and more consistent with commands written in C. A new configuration color.interactive variable is like color.diff and color.status, and controls if "git-add -i" uses color. A set of configuration variables, color.interactive.<slot>, are used to define what color is used for the prompt, header, and help text. For perl scripts, Git.pm provides $repo->get_color() method, which takes the slot name and the default color, and returns the terminal escape sequence to color the output text. $repo->get_colorbool() method can be used to check if color is set to be used for a given operation.
