dijit.form.Select always disabled

[Mike Wilcox]

After a revision of around 20733, the diji.form.Select broke. The dijit tests work, but none of the Selects in my app do. I tried to track down the exact reason but could not. It would appear the cause is from using setStore. When doing this, the widget does not recover, even when calling attr("disabled", false) with a timeout.

Attaching a test case.

Yah, I broke when select starts out w/no options and then the options are added later, I'll fix that.

(In [20741]) Intermediate checkin to get Select working again for when items are added to the drop down after the select has been created. Also remove special readonly handling for 1-item in the drop down, to better match normal select behavior. Refs #10274, fixes #10289 !strict.
