More elastic Custom Fields? edition

Currently, when we create a select/radio/checkbox Custom Field, we can choose which items should be selected by default, what are the items? labels and values and which items are active. Unfortunately, only the default value can be changed later.

It would be great if the items? labels, values (this might be tricky, as would require a cascading change in the custom_value table) and activeness was editable as well.

Also, the current implementation of editing the default value should change to be a list ? now I can define a checkbox list, select one of the items as the default, then re-edit the field and change the default to an altogether non-existent field.

// Currently, one could wonder what is the point of specifying non-active select/radio/checkbox item, if the items cannot be later activated/deactivated?
