epriestley 40680e459f Add a basic multipage form 
Summary:
Ref T2232. Very busy day on IRC so I feel like I've made 20 minutes of progress in 1-minute spurts here, but this adds the basics for a form that can have multiple pages and automatically handle pagination and reading to/from the request, objects and responses.

The UIExample is reasonably instructive. Basically, you make a form, add pages to the form, and add controls to the pages. The core flow control looks like this:

  if ($request->isFormPost()) {
    $form->readFromRequest($request);                 // (1)
    if ($form->isComplete()) {                        // (2)
      $response = $form->writeToResponse($response);  // (3)
      // Process result here.                         // (4)
    }
  } else {
    $form->readFromObject($object);                   // (5)
  }

The key parts are:

  # This reads the form state from the request, including reading all the inactive pages.
  # This tests if all pages are valid and the user just clicked "Done" on the last page.
  # This produces a "response", which might be writing to an object (for simpler forms) or creating a transaction record (for more complex forms).
  # Here, we would save the object or apply the transactions.
  # When the user views the form for the first time, we preload all the values from some object (which might just be empty).

Ultimate goal here is to fix repository creation to not be a terrible pit of awfulness.

There are probably a lot of rough edges and missing features still, but this seems to not be totally crazy.

I'm using two submit buttons with different names which doesn't work on IE7 or something, but we can JS our way out of that if we need to.

Test Plan: Paged forward and backward through the form.

README 

Phabricator is an open source collection of web applications which make it
easier to write, review, and share source code. Phabricator was developed at
Facebook.

This is an early release. It's pretty high-quality and usable, but under
active development so things may change quickly.
