ZScript Docs button does nothing

[Asuna Yuuki Nagato]

Steps to recreate:

1. ZScript->Compile ZScript...; 9-button "Compile ZScript" window appears
2. Click 'Docs' button

Should probably launch this (offline?) documentation:

This button is created in compilezscript.cpp

In CompileZScriptDialog::handleMessage we have:

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