- fixed "signal loops" causing StackOverFlowExceptions (now the signals can only take 10 "steps" between components per frame)

- parameter for changing the output value of And/Or components when the input conditions aren't met
- or components work properly now
- a limited number of signals (100) can be queued in a delay component
