Adapters should be separate from FuncUnit

Jasmine has changed it's approach to async execution in v2. This modifies the jasmine-funcunit adapter to take a done() callback into account, as opposed to waitsFor(). This illustrates the need to have independent, versioned adapters so that we can support FuncUnit with any version of QUnit, Jasmine or Mocha without re-versioning FuncUnit itself.

Start by examining the existing jasmine-funcunit adapter and how FuncUnit connects to the QUnit, Jasmine, and Mocha adapters. Separate the adapters so they can be versioned independently from FuncUnit, while preserving support for each test framework version. Done means framework adapters can change without re-versioning FuncUnit itself.
