TextBox: disabled textboxes aren't indicated

[bill]

I expected the text for disabled text boxes, combo boxes, data text boxes, etc. to be gray, to indicate that they can't be changed (and to match native styling), but nothing seems to change compared to enabled text boxes

http://download.dojotoolkit.org/release-1.1.0/dojo-release-1.1.0/dijit/tests/form/test_validate.html (see the euro currency example) demonstrates the problem.

Similar to #6087, about TextArea?.

(In [13362]) CSS fixes for TextArea? and TextBox? disabled and focused modes:

• make disabled TextBox? based widgets (like ComboBox?) have gray text, to disambiguate them from enabled states (fixes #6574).

• same for TextArea? and SimpleTextArea?. Exception is TextArea? on FF2, which is difficult because of the iframe (fixes #6087).

• make TextArea/SimpleTextArea? indicate focus with darker border, just like TextBox? based widgets (fixes #6470). Note that for TextArea? widget, _focused and _blurred where bad names for private methods, since they conflict w/the state variables used by FormWidget:setStateClass().

(In [13447]) Make themeTester.html have enabled and disabled versions of all the form widgets. Refs #6152, #6574, #6087

Also removed class="medium" affecting sizes on themeTester. Refs #6326.

And did some general cleanup/refactoring of tabs.
