ZScript Docs button does nothing

Should probably launch this (offline?) documentation:

https://www.zeldaclassic.com/zscript-docs

This button is created in compilezscript.cpp

In CompileZScriptDialog::handleMessage we have:

		case message:😃OCS:
			if(fileexists("docs/ZScript_Docs.html"😉)
				launch_file("docs/ZScript_Docs.html"😉;
			return false;
