Feature: named enum values

[raineorshine]

Currently Solidity enums are exposed as uints:

it('should have a myEnum property', () => {
  var contract = MyContract.deployed()
  return contract.myEnum.call(accounts[0]).then(myEnumResult => {
    assert.equal(myEnumResult.valueOf(), 1)
  })
})

It would be great for ether-pudding to expose named enum values so that the tests are not tightly coupled to the enum's underlying integer values:

assert.equal(myEnumResult.valueOf(), contract.deployed().MyEnum.SomeValue)

Enums are not exposed in the ABI, so we would need to parse the source code to map enum types to integer values.
