Revision 388309

DERBY-839 (Partial).  Internationalize Connection.java.  Also upgraded
the "i18n lint" test to be a little more intelligent, and to not exit
on the first failure.

Passes derbynetclientmats.  All changes are client-specific so derbyall
was not run.

Note there are some extra messages not currently being used.  These are
from the initial work Anurag did on this.  I'm just splitting up his
very big patch into smaller, more manageable pieces.
