 When js is enabled, and you save a widget, there are several issues with
 the current implementation:

  - If an error occurs (in the script or wherever), it's difficult to know
  - You cannot return an error message (short of using js form validation)
 to a user when he enters erroneous values
  - If the user enters values that get sanitized or auto-corrected by the
 update function, the widget still shows the junk entered by the user upon
 saving

 Suggested enhancement: output the results of update() and form() on the
 ajax, and replace the widget's current contents with their updated value.

 Marking this as a defect, rather than an enhancement, due to how
 complicated it makes writing a widget form without using Firebug.
