=begin
Adds some UI classes to the Symbol class.  These methods are prefixed with `ui`
to make their intent clear, and to provide a little bit of "namespacing"

    # alignment
    :left.nsalignment => NSTextAlignmentLeft

    # uicolors
    :black.uicolor => UIColor.blackColor

    :darkturquoise.uicolor => UIColor.blackColor

You can extend the defaults by adding entries:

    Symbol.css_colors[:my_color] = 0x123456

    :my_color.uicolor => UIColor
