Reorganize directory structure.

[gtanner]

Current code needs some reorganization as it is confusing where everything lives and the root dirctory is a flood of files that all server different purpuses.

Top level directories should be created to sort files into logical groupings:

src/

All source code (further breakdown should happen in this folder (plugins folder / etc, but will be handled in another task

pkg/

The build output

docs/

All supporting documentation (samples / etc)

tests/

Unit test code.

build/

Any build support code, test runners, test markup, etc.

thirdparty/ or lib/

Third party code (jWorkflow, jasmine, etc) that is needed for building / bundling / etc

/

root dir should really only include the JakeFile, README.md, license information.

I like that.
