synchronized highlighting

Relates to #288

synchronized particularly breaks the highlighting especially in a switch/case. Untested against Laurent’s dlang extension.

__gshared int test;
void main(string[] args) {
	synchronized ++test;
	switch (args.length) { // <- broke
	case 0:
		synchronized ++test;
		break; // <- broken, including this comment
	default: // <- broken, including this comment
	}
}
