[IronPython] Better dir() for Enum

I like the __doc__ idea a lot.  I don't think we want to go changing the semantics of dir, but obviously we can put anything we want in __doc__.

We're also planning in finally implementing help(), which would also presumably include this info, so ulitmately it'll only be one more character than dir().

Subject: [IronPython] Better dir() for Enum

Let's illustrate this feature request with an interactive session:

>>> import System

>>> dir(System.IO.FileMode)
['Append', 'CompareTo', 'Create', 'CreateNew', 'Equals', 'Finalize',
'Format', 'GetHashCode', 'GetName', 'GetNames', 'GetType',
'GetTypeCode', 'GetUnderlyingType', 'GetValues', 'IsDefined',
'MemberwiseClone', 'Open', 'OpenOrCreate', 'Parse', 'ToBoolean',
'ToByte', 'ToChar', 'ToDateTime', 'ToDecimal', 'ToDouble', 'ToInt16',
'ToInt32', 'ToInt64', 'ToObject', 'ToSByte', 'ToSingle', 'ToString',
'ToType', 'ToUInt16', 'ToUInt32', 'ToUInt64', 'Truncate', '__class__',
'__init__', '__module__', '__repr__', 'value__']

>>> sorted(System.Enum.GetNames(System.IO.FileMode))
['Append', 'Create', 'CreateNew', 'Open', 'OpenOrCreate', 'Truncate']

I think there's no doubt that the later output is more useful. But I'm
not sure whether this feature request interferes with other possible
features of IronPython.

If the above is undesirable, at least this could be improved:

>>> print System.IO.FileMode.__doc__
no documentation available
