TextArea readOnly bug - and solution

[Ronaldo]

Hi all,

I was trying to set a textarea to readonly, and it didn't work. Turned out that in 4.1 beta 2 the {cls} is missing, just as it was in the base class.

Ext.define('Ext.form.field.TextArea', {
   ...
    fieldSubTpl: [
        '<textarea id="{id}" {inputAttrTpl}',
        ...
            ' class="{fieldCls} {typeCls} {cls}" ',
        ...
        '</textarea>',

Thank you for the report.
