[web/data] Ignore disabled widgets in cw.utils.formContents() (closes #3544492)
17.12.1 Disabled controls : http://www.w3.org/TR/REC-html40/interact/forms.html#h-17.12.1
When set, the disabled attribute has the following effects on an element:
* Disabled controls do not receive focus.
* Disabled controls are skipped in tabbing navigation.
* Disabled controls cannot be successful.
The third one is the important one.
17.13.2 Successful controls : http://www.w3.org/TR/REC-html40/interact/forms.html#successful-controls
A successful control is "valid" for submission. Every successful control has
its control name paired with its current value as part of the submitted form
data set.
Bottom line, disable widgets should not be part of the names and values lists returned by formContents().
Schema of the data

First take a look at the data schema_ then try to remember that you are browsing
through a heap of data by applying stylesheets to the results of queries. This
site is not a content management system with items placed in folders. It is an
interface to a database which applies a view to retreived data.
