[Hibernate] New built-in type

[Emmanuel B. <emm...@hi...>]

I've added a new built-in type to support char[] into VARCHAR.
The current implementation serialize the array.

And now I'm thinking about Character[]
Mapping a array of Character into a VARCHAR does not make sense to me 
since there is no notion of null elements in a VARCHAR AFAIK.
The RI does that however. What do you think?

Character[] and Byte[] has to be supported as per the spec, but they do 
not make much sense to me.
