This was broken when we switched away from using StringStyleValues. While I was at it, I have implemented hsl/a() and the percentage syntax for rgb/a(). As a bonus, added `colors.html` as a test page for the various CSS color syntaxes, since nothing was testing rgb() or rgba() before. Much of the parsing code in LibGFX/Color.h seems to be centered around CSS color values, but this is not used by the new Parser. (And can't be used, because it requires a String value and we have a list of Tokens of some kind instead.) Maybe that should be removed from there when the new CSS parser is operational.
