MonoInput performer options load correctly.

Including defaults, when there are no options in
the .mkss file.
TODO: implement monoInput.doControl() for
each of the performer otption's controls.
Completed the MonoInput options dialog.

Also created a new namespace: _AP.utilities
containing functions that may be useful in more
than one other namespace.
Show/hide checkBoxes and masterVolume inputs.

These were previously disabled/enabled, but this
led to display problems when changing scores.
Also: moved the folowing functions to Utilties.js:
setDefaultValuetoBlue() and intArrayFromAttribute().
