If all the methods in an @AutoValue class are getters (getFoo() or isFoo()) then consider that each one defines a property called foo rather than getFoo. The user-visible change is that those names appear in the toString() of the generated class. The generated code is also a lot less surprising in this case. That's typically visible when you do code-completion on the AutoValue_Foo constructor in an IDE.

The main motivation for this change is that we will want to support both bar(x) and setBar(x) when we add builders, and that means supporting both bar() and getBar() as setters.

Bump auto-project dependencies to stable release versions and remove the now-obsolete common version stuff in the parent.

Also update the test the executes the open-source maven build so it properly executes against all of the sub-modules.

allow top-level classes with no package

FactoryWriter.getPackage() assumed that the fully qualified class name
would contain a package and hence failed with a
StringIndexOutOfBoundsException.
