Subject: [PATCH] Switch to 11 build target / source on javac.

Minor bit of cleanup in the ant scripts around the build src and target on javac, enabling use of Java 11 language features within processing itself. Note that the build is sustained on either 1.8 or 11 in terms of lanugage features but the code is no longer compatible with the Java 8 runtime due to backwards-incompatable changes made starting in Java 9.
