Stylin'!

Good afternoon,

We've got some big changes coming up, but we thought we'd do a release now so that you guys can pick up some fixes and enhancements we made:

• Sweet new stylings! (see above) There are now "canonical" Plottable colors in colors.ts.
• Gridlines at x=0 and y=0 now have the zeroline CSS class.
• CSS classes have been renamed: renderer, bar-renderer, line-renderer, area-renderer have been renamed to plot, bar-plot, line-plot, area-plot, respectively.
• Formatters are now simple functions that take in a single argument and returns a string. Factory methods exist in Formatters.ts.
• Axis.Numeric width calculation should work better now.
• Users can set the extra space between the tick labels and the outer edge of the axis using the gutter().
• Users can set the length of the end ticks independently with endTickLength().
• Plot.Line and Plot.Area can now project display properties based on the data:

areaPlot.project("fill", function(d) { return d.color; });

The first datum will be used to determine the display properties in these cases.
