Unescaped characters in Admin Name field cause issues in Atom feed reader

[dtiburon]

From a user:
I can't open the Women In Free Software with my feed reader (NewsFox)
because it claims that the feed isn't well formed. The WC3 Feed
Validation Service complains about an unescaped "&":

This feed does not validate.
line 7, column 24: XML parsing error: :7:24: not
well-formed (invalid token) [help]

This was something I (Aleta) recently edited in the Admin Name field under Planet Config. As a short-term solution, I replaced the ampersand with the word "and".

To do: Add escaping to characters in that field.
