move @xml:lang from <state> to <desc>

Instead of asserting that the @xml:lang of the <state> element is
English, I think it makes more sense to assert that the @xml:lang of the
enclosed <desc> element is English.  That way if someone wants to insert
a French <desc> they can simply do so.
Added additional titles

Added roles for Patriarch, Catholicos, Monk, Metropolitan, Deacon,
Abbot, and Maphryono.  I also made "presbyter" equal "priest".
Added abbreviation metr.

I discovered an entry uses "Metr." instead of metropolitan so I included
this as an abbreviation in the state.xsl/$roles variable.
