Moved user-defined ElementMapping initialization from Driver to FOUserAgent.

Moved only "string" method, the version we use internally--probably sufficient
for others' work as well.  (Note: an additional unused FOUserAgent object will
be created in driver during command-line use--cp. its no-param constructor vs.
setUserAgent() call in apps.Fop; this will need to be ironed out at some time.)
