[Murray Cumming <murrayc src gnome org>]

commit 63474d78ec5ece94e007823e17a2dfa7ff68c990
Author: Murray Cumming <murrayc murrayc com>

    Do not blank the data when showing the field definitions dialog.
    
    * glom/frame_glom.cc: do_menu_developer_fields(): Only blank the data
    view if using SQLite, which requires it, because it looks like a bug to
    the user.
