This adds the beginnings of unit test support for Spina. We now have a

npm run test command that will invoke Jasmine on our test suite,

verifying that we don't regress and that everything behaves as expected.
For DOM-related tests (needed for BaseView), we make use of jsdom,

which simulates a DOM. This works along with jQuery. An in-memory

environment is set up before tests are run. No browser environment is

required for this.
Currently, there are no tests, but those will be coming along with some

in-progress work to fix and tighten up base object support.

Tested along with in-progress unit tests, which pass.
