Add support for the standard ANSI escape codes

[JoeMerten]

For my project, I need to have support of standard ANSI escape codes rendering in Xcode (see http://en.wikipedia.org/wiki/ANSI_escape_code). There was a pull request #12 from mkeiser on June 2014 but it wasn't merged.
Is there a reason why not want to make XcodeColors able to understand standard ANSI escape codes?
IMHO there should be no conflict when parsing both current esc[fg...; and standard ANSI simultaneously, isn't it?

Standard ANSI color codes would be great. I'm using Appcode as an IDE and therefore the use of XcodeColors isn't possible.

@robbiehanson do you have any plans to fully support standard ANSI codes at all?
Right now, outputting to the Xcode console works fine, but outputting to a file really doesn't do any good...
