Discussion #1070 proposed that rotate, like move, copy and delete, works on
the whole group once one of its items is clicked. Rotate (Space) turned
each member on its own spot instead, so rotating a group pulled it apart:
two grouped texts side by side ended up each turned in place, no longer
side by side.
When the selection is exactly one whole group -- wires aside, which follow
their symbols -- Rotate now turns it as one piece around its centre, as
"Pivoter le groupe" (Shift+Space) already does
(ItemGroups::soleWholeGroup()). Any other selection, including a single
member picked out of its group, rotates as before.
In the GUI, on two grouped texts selected by one click: Space on master
leaves both where they were, turned; here it gives exactly what
Shift+Space gives on both (both texts swung around the group's centre).
tst_itemgroups: 4 new checks; without the whole-group condition, a
picked member counts as a group and fails. ctest 24/24.

Clicking an item of a group selects the whole group (#1070). Clicking
again on one of its items is meant to select just that item, to edit it
on its own -- what discussion #1070 proposed -- but the second click
selected the whole group again: Qt left only the clicked item selected on
release, and the group completion pulled the others back in.
A press on a member of a group that is selected whole now notes that
member (ItemGroups::memberToPick(), which also finds the member when the
click lands on a symbol's own text). If the click ends without a drag and
Qt has left only that member selected, the selection stays so. A drag
still moves the whole group; Ctrl+click keeps its meaning; a group of one
is not picked from.
In the GUI, on two grouped texts: one click then Delete removes both
(master and this); click, click again, Delete removes only the clicked
text here, both on master; dragging after one click moves both texts by
the same amount on both. tst_itemgroups: 5 new checks; removing the
whole-group or the group-of-one condition fails one each. ctest 24/24.

Symbols, free texts, shapes and pictures can be grouped from the Edit
menu, the selection's context menu or the command search. Clicking one
member selects the group, so moving, copying and deleting act on all of
it; Ctrl+click on a member deselects the group; a rubber band touching
part of a group selects all of it when released. No default shortcut:
Ctrl+G is "jump to element".
A group is not an object in the scene. Each member keeps its place and
carries the group's uuid (QGraphicsItem::data()), saved as a "group"
attribute written only when set: a project without groups saves exactly
as before, and older versions open a grouped one and ignore the groups.
Re-parenting under a QGraphicsItemGroup would have made every member's
position group-relative; ElementTextItemGroup already needs nine special
cases for that.
- Selection is completed on clicks and at the end of a rubber band, not
on every selectionChanged(): export, search and Tab select items
themselves and must not have groups pulled back in.
- Project database: group_uuid on element, shape, independent_text and
image, kept in step by projectDataBase::itemGroupChanged().
- Paste and folio duplication give each source group one new uuid.
- Undo of Ungroup restores each item's exact group.
Builds on #1065 (uuids and database rows for texts, shapes and images).
