CSS Effects ( textShadow, -linear-gradient, etc. )

Its great that Cufon is equip with the abilities to add css text effects such as textShadow, but they need to be called when calling cufon.replace(). I added a function that allows you to use these kind of effects in this module, and rolled a patch for it. To use it now, you can write selectors with CSS style syntax on it's settings page like so:

h2 { color:-linear-gradient(#777, #000); }

or even...

h2 {
  textShadow:0 1px #fff;
  color:-linear-gradient(#777, #000);
}

I've tested syntax and browser capabilities pretty thoroughly.
