Always pass valueArray to menuRenderer

[chronick]

My application's designers wish to display a visual indicator for selected items instead of hiding them from the dropdown list when using a multi selector. Always passing the valueArray to the menu renderer seemed to be the best and least-impact way to do so.

The default behavior of the select box appears to be unaffected by this change, since the actual hiding of options happens in the default filterOptions function.

Coverage remained the same at 92.874% when pulling 75f4050 on chronick:multi-valuearray into 196c7bb on JedWatson:master.

Just encountered this and @chronick 's fork worked like a charm.

Conditionally pass in valueArray does not make sense to me either.

@chronick thanks for this, this particular fix has been pulled into master as part of #1850
