Ui.dialog close API should have a force mode, non cancelable with events

Added to GitHub repos. Pull request submitted - https://github.com/jquery/jquery-ui/pull/1218

Please take a look.

Why do you need this?

Consider the below case,

1. There is a modal form to collect input from user.

2. User can close the dialog by clicking on - "Cancel" or close ui button.

4. Add a beforeClose listener to check if the user has entered any value.

5. If user has not entered any value, continue to end. Else go to 5.

6. Open a modal confirm, informing the user about unsaved data that might be lost. Two actions -

A. Confirm close and lose data

B. Cancel and return to form

7. If A is chosen, close the modal confirm, and call modal form ("close") API

8. If B is chosen, close the modal confirm

Currently after step 7, step 4 is invoked again and keeps looping.

The requirement is to modify the close API to allow force close without firing the before close event.

A similar analogy can be made to that of setting a value to the input programmatically, which doesn't trigger the change event, unless programmatically triggered.

Hope this helps in understanding the need.

You can very easily handle this with a flag in your own code instead of adding a flag to the dialog API.

Ah yes. This can be handled in the code. This is like saying $(document).ready() is not required as it can be easily handled by using window.onload.

But this addition will be more useful as part of the API. Helps reduce a loop for any dev using jquery ui. Just my two cents.
