Arrays of arrays causes failure in UDTCompiler

[ritchiecarroll]

Right now when an array type is created in the UI and added to a new UDT, a separate array based type appears in the drop as an array, e.g., byte[].

If you now try to use this new type as an array the UDTCompiler throws an exception.

We need to modify the UI to filter array types out of the dropdown.

I just disabled the array check box if the user selects an array from the types list
