I noticed that mediawiki has the MySQL root account name hardcoded in,
even though many database installations use a different username as the
administrator as a bit of added security, or for convenience, or whatever.
I've created a simple patch that gives the installer an extra field for
'root username', defaulted to "root". It applies cleanly to versions
>=
1.3.3
