* Fix Wichert's previous fix to check ignoreContext the correct way. [davisagli]
1.0b6
------------------
* Do not query the datamanager if we should ignore the context. Fixes http://code.google.com/p/dexterity/issues/detail?id=120 [wichert]
1.0b5
------------------
* Avoiding reading file uploads to determine their size. [wichert]
1.0b4
------------------
* Rename nochange to action, since the field was being used to specify which action to take. [wichert]
* Disabled state was being applied to the wrong tag (span instead of the input) for images and files, and we're not using tabindex anymore. [limi]
1.0b3
------------------
* Fix bug where fields that failed validation for requiredness mistakenly interpret the empty FileUpload in the request as a real value. [davisagli]
* Fix bug where fields were not validated for requiredness or field constraints. [davisagli]
* In lieu of real image scaling, at least make sure the thumbnail used on the image input widget has the correct aspect ratio. Fixes http://code.google.com/p/dexterity/issues/detail?id=77 [davisagli]
1.0b2
------------------
* Make the widget more robust to validation errors elsewhere in the form. Fixes http://code.google.com/p/dexterity/issues/detail?id=76. [optilude]
