New CSS parser for JavaFX

[Michael Strauß]

I've written up a proposal to implement a new CSS parser for JavaFX:
https://gist.github.com/mstr2/f416996caf48e11193f0b6a5883a3926

The goal is not add new features at this point, but to resolve some
long-standing issues with the existing CSS parsing (though if you read
carefully, you might spot a new feature).

I'm interested in your opinion whether this is a good idea to move forward.
