Support for hyphenated component names

A candidate fix for:
#296

Not sure if you'll like this solution, as it's pragmatic rather than being 100% robust...

Other solutions I considered:

• Duplicating the entire styleParser code out of A-Frame utils into event-set, except for the camel casing. That seemed unwieldy.
• Changing the A-Frame utils API to either export the styleParse function or have an optional parameter on styleParse.parse to control whether or not camel casing happened. I was hoping for a fix that was contained within this repo, rather than having dependencies on another repo, with all the version issues that would ensue...

So having ruled out those two approaches, I ended up using A-Frame utils styleParser.parse, and then patching up the results as best I could.

As per the comments in the index.js file, that's not a 100% robust solution, but much better than the current implemetation. The problematic cases are all fairly pathological...

@dmarcos - Any comments on this?

Maybe the better solution will be fix this on aframe changing the AFRAME.utils.styleParser.stringify() to return with dash. So, with this, the aframe-event-set-component could to use stringify on props to return. The parser transforms to camel case and stringify dosn't come back to kebab case is a strange behavior.
