EmailAddress charset uninitialized reference.

[slim]

Bug:
-------
In EmailAddress.cs, the charset is never initialized by default causing a Null Reference exception:

Reproduce:
-----------------
Send an email to an address that needs to be encoded (eg "
Thomas LJmann JRgensen"), I get an error:

System.NullReferenceException: Object reference not set to an instance of an object.

Solution:
------------
In EmailAddress.cs, set default:

_charset=System.Text.Encoding.ASCII;

Hi-

I've fixed this in the latest version. I set the default is iso-8859-1, since QP is not required for ASCII.

Thanks,
