plantuml.jar updated to v8004.

Replaced "java -jar" invocation with predefined contents in plantuml.el
CAUTION: plantuml.el file also has whitespace change ! Grep for BDS

java -jar ~/.emacs.d/bin/plantuml.jar -language > util/plantuml.language

The reason for this is the "out of heap" message thrown by Java while Emacs startup.
Now java is not even run at all!
