[app.source] Common source into libraries

If you find yourself cutting and pasting source code from a previous project to start a new one, seriously consider moving that source into a common library.  Cutting and pasting code is the fastest way to get stale code into a project.  Instead, refer to a common JAR library and load up the source for reference purposes only.

Any changes made to the common JAR library to help the new project should not be specific only to the new project, and absolutely do not add dependencies from the common JAR project back into the new project.
