[AutoCompleter] Enabling a disabled AutoCompleter in IE does not change the style

[haysmark]

AutoCompleter? #3 still looks disabled when you enable it. onValueChange is not being called, so something is still disabled.

[haysmark]

Has to do with dom.disabled vs javascript.disabled. AutoCompleter? was doing both manually; now it calls FormElement?'s enable and disable and disables the textbox with the dom attribute.

(In [8618]) (proxy checkin for Mark Hays, IBM, CCLA on file) Fixes #2935, #2938, #2962, #2992, #2936, #2937, #2977, #2981, #2999, #3000, #3004, #2812 Adds new popup code, only one Calendar for all DateTextboxes?, only one menu for AutoCompleters/Selects?. DateTextbox? works with new dijit._Calendar. DateTextbox? carries over min/max to the Calendar. All files much more consistent with the Dojo style guidelines.
