[DotGNU]System.Security.SecurityElement patch

[Carl-Adam Brengesjö]

Noticed that the set method of the `Attributes' property didn't actually save 
the values, it just walked the hashtable, checked it's values for invalid 
data and then just returned. (see attached patch).

And I also though of something else, as the hashtable are being constructed 
each time it's being fetched (get_Attributes) you cant add attributes 
afterwards, like:

  SecurityElement se = new SecurityElement("user", "foo");
  se.Attributes.Add("group", "bar"); // won't have any effect

the plain XML should look like this:
  <user group="bar">foo</user>
but looks like this:
  <user>foo</user>

But the current implementation cannot acheive this. Should it be like this, or 
is it something that should be done?
