Relative alignment when multiple objects are selected at ounce - Remove the options First Selected and Last Selected

Summary:

In "Object/Align and Distribute"

If you select multiple objects by defining a selection zone (mouse drag), 2 options does not make sens:

• last selected
• first selected

This dialog should have 3 remembered last used states:

• When a single item is selected (see issue #5060).
• When one or more item are selected individually (see issue #5060).
• When no objects are selected individually (drag selection or select same ...):
  • Hide Irelevant options for selection type
  • Add a third remembered state (single object, sequential multiselection and non sequential multiselection)
  • Disable unsignificant distribution commands depending on selection type

Current

(see issue #5060)
