/**
* Displays a new message box, or reinitializes an existing message box, based on the config options

* The following config object properties are supported:
* <pre>
Property Type Description
---------- --------------- ------------------------------------------------------------------------------------
animEl String/Element An id or Element from which the message box should animate as it opens and
closes (defaults to undefined)
buttons Object/Boolean A button config object (e.g., Roo.MessageBox.OKCANCEL or {ok:'Foo',
cancel:'Bar'}), or false to not show any buttons (defaults to false)
closable Boolean False to hide the top-right close button (defaults to true). Note that
progress and wait dialogs will ignore this property and always hide the
close button as they can only be closed programmatically.
cls String A custom CSS class to apply to the message box element
defaultTextHeight Number The default height in pixels of the message box's multiline textarea if
displayed (defaults to 75)
fn Function A callback function to execute after closing the dialog. The arguments to the
function will be btn (the name of the button that was clicked, if applicable,
e.g. "ok"), and text (the value of the active text field, if applicable).
Progress and wait dialogs will ignore this option since they do not respond to
user actions and can only be closed programmatically, so any required function
should be called by the same code after it closes the dialog.
icon String A CSS class that provides a background image to be used as an icon for
the dialog (e.g., Roo.MessageBox.WARNING or 'custom-class', defaults to '')
maxWidth Number The maximum width in pixels of the message box (defaults to 600)
minWidth Number The minimum width in pixels of the message box (defaults to 100)
modal Boolean False to allow user interaction with the page while the message box is
displayed (defaults to true)
msg String A string that will replace the existing message box body text (defaults
to the XHTML-compliant non-breaking space character ' ')
multiline Boolean True to prompt the user to enter multi-line text (defaults to false)
progress Boolean True to display a progress bar (defaults to false)
progressText String The text to display inside the progress bar if progress = true (defaults to '')
prompt Boolean True to prompt the user to enter single-line text (defaults to false)
proxyDrag Boolean True to display a lightweight proxy while dragging (defaults to false)
title String The title text
value String The string value to set into the active textbox element if displayed
wait Boolean True to display a progress bar (defaults to false)
width Number The width of the dialog in pixels
</pre>
*
* Example usage:
* <pre><code>
Roo.Msg.show({
title: 'Address',
msg: 'Please enter your address:',
width: 300,
buttons: Roo.MessageBox.OKCANCEL,
multiline: true,
fn: saveAddress,
