Make ignorehitpause block affect its nested blocks in ZSS

ignorehitpause if playerno = 2 {
	if time > -1 {
		text{
			text: "This is a text";
			pos: 100,100
		}
	}
}

Running the code above, text will fail to draw during a hit pause due to 'if time > -1' subblock not inheriting the 'ignorehitpause' attribute from the main block in the compiler. This commit attempts to fix that assuming this behavior makes more sense.
