Charmingly Simple Styling for cljfx

Rationale

JavaFX is designed to use CSS files for styling. CSS has it's own set of problems such as selectors unexpectedly overriding each other and having unclear priority. Because of that, using inline styles is much more predictable, and with cljfx, where styles can be described as maps, also composable.

Unfortunately, CSS is unavoidable, because controls don't provide access to their internal nodes, and they can be targeted only with CSS selectors. What's worse, JavaFX does not allow loading CSS from strings or some other data structures, instead expecting an URL pointing to a CSS file. This leads to slow iteration cycle on styling and also to duplication of styling information in CSS and code.

Charmingly Simple Styling is a solution to these problems: it provides a way to configure application style using clojure data structures, while also allowing to construct special URLs that contain CSS information for styling JavaFX nodes, derived from the same data structures.
