Caught a DynamicStyle error. The test string for styled UI text has a nice button in it now.
ButtonStyle also had a state change issue that I worked out.

Separated style sigils to their own class. This UTF stuff is hell, I tell ya.
Fixing some of the UTF8-related bugs in UIBody and StyleSet. As a result of using UTF8-friendly regular expressions, it doesn't build for Mac anymore! :-/
Neko target now has feature parity with the HTML5 target. Mac target compiles, but won't run without figuring out the PCRE UTF-8 issue.
