Renamed init.go to uitask.go because that should have been done ages ago.

-// If initialization fails, Go returns an error and Ready is not pulsed.
-// Otherwise, Go does not return to its caller until Stop is pulsed, at which point Go() will return nil.

-// Pulsing Stop will cause Go() to return immediately; the programmer is responsible for cleaning up (for instance, hiding open Windows) beforehand.

-// It is not safe to call ui.Go() in a goroutine. It must be called directly from main(). This means if your code calls other code-modal servers (such as http.ListenAndServe()), they must be run from goroutines. (This is due to limitations in various OSs, such as Mac OS X.)

-// Go() does not process the command line for flags (that is, it does not call flag.Parse()), nor does package ui add any of the underlying toolkit's supported command-line flags.
-// If you must, and if the toolkit also has environment variable equivalents to these flags (for instance, GTK+), use those instead.
