to-do:

- escape button
- loading animation
- busy text
- the actual content div should not have padding.

change log:
14.07.2009
- now preventing double click (it won't try to open another fumodal window)

20.05.2009
- use fade:false to stop animations

17.05.2009
- now you can set the z-index of the modal window

20.05.2008 
- window content width
- setting content div
