Clean up option --moduleName.

Change moduleName option to [true|false|default] and delegate
default to each module transformer.
Set the default for moduleName to 'default'.
Pass options to ModuleTransformers via arguments rather than module exports.
Create transformOptions view dynamically from local options object.	
Set moduleName false for single file compile, true for bundles.

Fixes #1588
The point of `ignored` is that this function does not care what it is, it does not use the value.  All the transform constructors need the same parameter list, but this one does not use the second argument.
