- implemented rest methods
-- PUT new blacklists with or without content
-- GET names of existing blacklists
-- POST one new black list entiry to an existing blacklist
-- POST multiple new black list entiries to an existing blacklist
-- DELETE a black list entiriy from an existing blacklist (!BUG)

- added some jars to the pom for content handling. A good glassfish
should handle the war without them (but the newest version wont and
TomEE and Tomcat are bad as well)
