Metacat

fixes for creating SM for legacy docs

uncommenting tests

use detected document encoding or Metacat's default encoding (UTF-8)

include shared method in superclass

create another test for various i18n features including eml 2.1.1
http://bugzilla.ecoinformatics.org/show_bug.cgi?id=2495

uncomment the other test cases and make sure we do the clean up when the tests are complete (delete the uploaded documents)

use detected XML encoding when reading/writing files
use UTF-8 as default when performing queries in the DB (assume DB is using UTF-8)
remove as many PrintWriters (uses system default character encoding only) as possible and construct OutputStreamWriters where explicit encoding can be given....

fix for paths with semi-colons or other 'reserved' characters in them for D1 rest services

correct the prolog

changed test to use actual semi-colons instead of colons
