Modal dialog for enrollment

The enroll facet has been converted into a dialog box. This dialog
box will appear when the user clicks the enroll button above the
association list. When the user clicks the enroll button in the
dialog box, the new associations will be created, then the list will
be refreshed to show the changes.

The SerialAssociator and BulkAssociator have been modified to accept
an on_success function which will be called when the whole operation
is completed successfully. This is used to refresh the list and close
the dialog box appropriately.

Some other changes were also made to improve code clarity.
