Forward port of #346202 Fieldgroup: let the 'simple' template be overridable (thks fiskit) + allow template variants.

Forward port of #374213 by rpanna - Fieldgroup: All field instances removed their groups when one instance is deleted from a content type.

#256141 Add old updates back to fieldgroup.install for situations where the module was briefly enabled and then disabled and never used so the update process doesn't throw an error for the missing updates.

#227439, #227437, #227945 Rework field and widget type handling to simplify the intial screen when choosing a field and widget type by making it a two-step process where you see only the widgets that apply to the field. Move the setting of the field label to the same place where you set the field name. Change the field edit screen to keep it from showing all the different widgets again and instead just display the current widget. Then add a button to change the widget which will take you to another screen to make the change since the rest of the page will need to change when the widget changes. Keep the changes to the widget label  in that separate process, too, since that affects the menu tabs that need to be changed before redirecting back to the main page.

All working well except that changing the widget for an existing field is not redirecting back to the field edit page as it should.
