Title: Features for easier explaining of reactivity

- makeReactiveBinding: Turns a "regular" variable into a reactive.
No need to use reactiveValues() for simple reactivity.
- setAutoflush (not exported): Causes flushReact() to be called
each time something is executed at the R console top-level.
- options(shiny.suppressMissingContextError=TRUE): Prevents the
"Operation not allowed without an active reactive context" error
when attempting to read a reactive value or expression from the
console.
