This patch introduces the GUI::SyntaxHighlighter class, which can be attached to a GUI::TextEditor to provide syntax highlighting. The C++ syntax highlighting from HackStudio becomes a new class called GUI::CppSyntaxHighlighter. This will make it possible to get C++ syntax highlighting in any app that uses a GUI::TextEditor. :^) Sidenote: It does feel a bit weird having a C++ lexer in a GUI toolkit library, and we'll probably end up moving this out to a separate place as this functionality grows larger.
