Updates SQL DDL to don't forget about primary keys

It seems composite keys are not yet correctly handled (it should create
a single primary key with the composite properties instead of multiple
primary keys)

Merge branch 'master' of github.com:dresende/node-orm2

* 'master' of github.com:dresende/node-orm2:
  make some Model methods defined by `defineProperty` writable so they can be mocked by test suites in non-integration tests. - writable added to some model instance defineProperty calls, some properties were left alone because they were static or had unknown function (isShell for example) - added a model-remove test that currently only tests the writable aspect (there appears to be no direct test of this function, other than from the hooks tests)
