This PR upgrades the existing forms to the new API,
while leaving a copy for existing users.
The current forms will be the default until RC4, at
which point we will switch the default to the new API
but still retain a link to the old forms API.
After RC5 the old API docs will be completely removed.
Update gulpfile and project to add a tsconfig to protractor test folders
Change all sample e2e-spec.js -> e2e-spec.ts
Split typings between e2e-spec & app code
Use same config for all e2e tests
Only 1/3 e2e specs truly converted.
Most don't pass because they fail TS transpile by Protractor due to missing type annotations
