Updated to utilize blocking asynchronous code so that clicking doesn't accidentally stack up or require math to try and avoid overlapping. This removes the pollingLength from the SafewayClicker, but moves a delay to the Clicker.
This also likely updates some selectors that may have been old or too generalized if I didn't already do that.
