Add support for human friendly abbreviations on large numbers

[aaaaron]

My project was dealing with very large numbers, and the text values were overflowing the arc. This fork adds two new options:

    // humanFriendly : bool
    // convert large numbers for min, max, value to human friendly (e.g. 1234567 -> 1.23M)
    humanFriendly : (config.humanFriendly) ? config.humanFriendly : false,

    // humanFriendlyDecimal : int
    // number of decimal places for our human friendly number to contain
    humanFriendlyDecimal : (config.humanFriendlyDecimal) ? config.humanFriendlyDecimal : 0,

Here's an example of what it looks like in use: http://i.imgur.com/jDEnT.png

The actual code to do the conversion was extracted from http://stackoverflow.com/questions/2692323/code-golf-friendly-number-abbreviator and made to be a bit easier to read.

Hey aaaaron, this is great! I did some quick testing, works like a charm. Thanks for the effort, I'll make sure your name finds its way into credits once I finally find the time to update the site and download package :)
