- make every object calling getBinding:forObject: aware of this change
- implement _CPCheckBoxValueBinder to handle binding to the value of a checkbox Closes: #1083
- re-implement CPTextField's behavior for controller markers using the new binder class
- disabled some tests that are not compliant with Cocoa
- Checkbox and radio selected states would not show in the images. It turns out that the image and alternate image cannot be encoded->decoded->set without messing up the theme, and unfortunately the theme blending task (during a jake build) would do so. So for now this means that we cannot encode non-theme images with a button class, which is unlikely to happen.
- Since we cannot access themes in the NS classes, I went ahead and started to make some constants in a few control classes so that the values can be changed in one place and affect the theme and nib2cib.
