In a details page, usually any changes done to the fields will not be
applied until the user clicks the Update button. However, if the page
contains an association table, any addition/deletion to the table will
be applied immediately.

To avoid any confusion, the user is now required to save or reset all
changes to the page before modifying the association. A dialog box will
appear if the page contains any unsaved changes.

The association config has been removed because it incorrectly assumes there is only one association between two entities. Now each association is defined separately using association facets.

The service.py has been modified to specify the correct relationships. The API.txt has been updated.

Previously the IPA.details_list_section can only be used with widgets
that generates <dd> tag because it uses the following structure:

<dl>
  <dt>Telephone Number:</dt>
  <span name="teleponenumber">
    <dd>111-1111</dd>
    <dd>222-2222</dd>
  </span>
</dl>

The <dd> tag was previously used to handle multi-valued attributes.
Since multi-valued attributes are now handled by the recently added
IPA.multivalued_text_widget, the structure can be changed as follows:

<dl>
  <dt>Telephone Number:</dt>
  <dd>
    <span name="telephonenumber">
      <div>111-1111</div>
      <div>222-2222</div>
    </span>
  </dd>
</dl>

This allows IPA.details_list_section to be used with any widgets
without requiring the <dd> tag.

The reset and is_dirty functionality for permission has been fixed.
New widgets have been created for select and a collection of checkboxes.
New test data files have been added for each target type.

This patch fixes several issues in delegation UI:

When adding a new delegation, only the first attribute selected
was saved. Now all attributes will be saved properly.

When loading the details page, the custom widgets did not store
the original values properly so is_dirty() did not work correctly.
Now this has been fixed except for the memberof attribute because
of these issues:

 - https://fedorahosted.org/freeipa/ticket/870

When saving the details page, the attrs were saved as an array
which was rejected by the server. Now it is stored as comma-
separated list.
