Bug 15869: Change framework on overlay

This patch allows for selection of framework to use when overlaying
records - by default it is set to keep the initial framework

To test:
 1 - Create some records using one framework
 2 - Export the records
 3 - Edit the records to add fields not in original framework
 4 - Stage records using a rule that will find matches
 5 - Import
 6 - Note records contain new fields on display, but they are lost on edit
 7 - Apply patch
 8 - Stage records again
 9 - Select a framework that contains the new fields on import
10 - Import records
11 - Note records now use selected framework and are displayed/edited
correctly
