MongoDB supports uniqueness constraint on compound indexes, but plugin does not

the "compoundIndex" syntax in mapping config currently doesn't have an option for making a compound index have a uniqueness constraint.

You'd think you could do something like:

static mapping =

{ compoundIndex a:1, b:2, indexAttributes:[unique:true] }

But if you do, it simply fails to create the index.
