hammer: Fix Moray and Scottish King wintering.

Delay disband question until normal disband phase.
Allow staying even if over castle limit since you may want to be
able to disband another unit to keep Moray or the King).

Skip question completely if already at home or home is occupied.

Improve UI for Edward wintering -- can click England to disband,
and added button for wintering.
