Table model for JSON data

I'm to lazy to deal with XML and CSV is not an option. Therefor a created a Table class to deal with JSON data I receive from the server. It is even simpler than the CSV version- no parsing - just call eval(). I havn't tested putting a format on columns though. Here you go:

Use or include in 2.0 final at your own risk ...
