Integer type must have numerical suffix for uint but not for uint256

[reiven]

Hi!

Taking an example ERC20 contract with the following definition:

  function balanceOf(address _owner) constant returns (uint balance) {
    return balances[_owner];
  }

Executing a call() to the contract with uint var type i got this error:

>>> c.call(contract_addr, 'balanceOf(address)', ['0x00fC8E759f5941F54aD61e7716B7e5163D9CFA83'], ['uint'])
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "ethjsonrpc/client.py", line 120, in call
    return decode_abi(result_types, response[2:].decode('hex'))
  File "/hidden_path/local/lib/python2.7/site-packages/ethereum/abi.py", line 756, in decode_abi
    proctypes = [process_type(typ) for typ in types]
  File "/hidden_path/local/lib/python2.7/site-packages/ethereum/abi.py", line 623, in process_type
    "Integer type must have numerical suffix"
AssertionError: Integer type must have numerical suffix

but passing uint256 it works like a charm

>>> c.call(contract_addr, 'balanceOf(address)', ['0x00fC8E759f5941F54aD61e7716B7e5163D9CFA83'], ['uint256'])

BTW: i'm using an already patched version of the lib for 0x prefixes
