reflex-jsx-0.1.0.0: Use jsx-like syntax in Reflex

`reflex-jsx` is a library for writing jsx-like syntax in reflex code. This can be useful for situations where you have a large block of HTML with some styles, and it would be easier to read as actual HTML than various reflex functions. It's implemented as a QuasiQuoter, so you just import the jsx function from ReflexJsx and generate the equivalent functions that would run inside of a "MonadWidget t m". Not only can you generate a block of static HTML/CSS, but you can also splice in your own nodes that implement "MonadWidget t m", string attribute values, or even entire dynamic attribute maps.
