 We keep discovering new bugs for the AJAX in the list tables. Some current
 ones include issues with pushState (browser history is broken), bulk
 actions URI redirects and resets (which is a worse issue for usability
 than we thought). These strike at the core of the AJAX component. These
 are not easy to address, and will require some new API in some cases (such
 as transients for updated notices).

 The leads have discussed this and the decision is to remove AJAX from the
 list tables for 3.1. Without AJAX, the user functionality is unchanged
 from 3.0. This allows the re-architecture to be spread over multiple
 releases.

 Considerations:

  1. Don't enqueue the JavaScript.

  2. Don't add the ajax nonce fields or any spinners.

  3. The top pagination input doesn't work. Solution is to only have the
 pagination input on the top.

  4. The search box button shouldn't have a name.

  5. Sorting needs to kick back to page one.

  6. Remove the filters in get_list_table() and merge get_list_table() and
 require_list_table() into a private _get_list_table(). Mark all tables as
 private.

  7. The architecture of the list tables needs to be reviewed this week for
 potential changes. Right now it isn't at the state where we are
 comfortable with release, especially when considering future requirements
 for backwards compatibility. By removing the JS for 3.1, we can spend the
 next week getting the classes exactly how we want them.

 Patch to follow shortly.
