this adds two new methods to LoopUI.js, setBusyLoading and
clearBusyLoading, and one new state variable, busyLoadingCount, for
supporting the blocking of user clicking during async back end calls
that might take a bit of time to return. Blocking the user from clicking
on a component box is implemented as an important first case use, as
well as all PerformAction calls.
