Release 0.1.9

Release 0.1.9
-------------------
Changes since Release 0.1.8:

* Created org.virtualmock.VMFactory as entry point into VirtualMock framework.

* VM framework initialization was moved from VM to VMFactory.

* Changed core org.virtualmock.VM class to be an instance instead of having all static methods. org.virtualmock.VM is now obtained from org.virtualmock.VMFactory.createVM().

* Fixed some problems with VM unit tests. Unit tests are now run separately from functional tests.

* Reorganized unit test package structure to match org.virtualmock.* packaage structure.

* Removed Rules that didn't have any real use after I though about it, and made comments that some more may be deleted depending on how the API evolves.
