OerrLock resource

If oerrLock is true, the emulator will fully lock the keyboard in the event of an operator error. Only a Reset will clear the error. This is how real 3270 terminals work.

If the value is false, operator errors can be cleared by pressing one of the cursor-movement keys (&#x2191;, &#x2193;, &#x2190;, &#x2192;, &#x21b2;, &#x21e5;, &#x21e4; or Home).
