Changes

Remove global cursor usages

Blindy replace ActiveHand => self activeHand in morphs

Safely delete and show morphs when they are not in the world

More ActiveHand => self activeHand

More ActiveHand =>  morph activeHand  - cleanup tests that hardcoded
world/Hand access

Fix strange dependency between rectangle and world.

Replace ActiveHand users outside of morphic by (still not good) self
currentWorld activeHand

No more references to ActiveHand

Handle Morphs that access the hand before being installed in a world

Obtain hand from world argument

Replace ActiveEvent => morph activeHand lastEvent

Remove global ActiveEvent

Set an owner to menus. Otherwise they don't have a world to access.

Make spotter take keyboard focus after open and not before

Fix broken tests -> no focus is taken if morph is not installed in the
world

Revert takeKeyboardFocus changes in morph. Keyboard focus should we
always taken. Users should make sure the morph is shown.

GLMPopper should make sure it is shown before taking focus.

GLMScrollPaneBrick should not initialize listeners to global state
before it is shown

GLMPopper focus should be on the internal text morph, not the popper

Restore cursor change, cursor change does not take effect if it does not
pass through the hand

Set hand as active hand in morph instead of global

Fix tests:  - define #privateOwner: in SpMockMenu  - make
#takeKeyboardFocus work even if #activeHand is not active  - remove
unused temp from #becomeActiveDuring:  - modify baseline to avoid
incorrect CurrentCursor claspool initialization
