Four bugs fixed:
- Don't clear orders when changing the activity. In the future it will
be possible to have an activity while under orders.
- Don't sentry a unit when boarding a ship unless the orders are over.
This check is now duplicated in move_unit and execute_orders (since
orders code shouldn't go into move_unit). In the future it can be
removed from move_unit.
- Don't focus a unit when it's under orders. One additional place in
find_best_focus_candidate had to check for unit_has_orders(). Otherwise
if _every_ unit had orders one of them would be focused.
- Reinstate the enum activity_type enumeration. Since these values are
put in the savegame we can't just remove ACTIVITY_PATROL without
completely breaking things. Instead it's renamed as
ACTIVITY_PATROL_UNUSED and checked for when loading savegames.
Savegame behavior is now like this:
- When loading an old game, patrol routes are lost.
- When loading an old game, goto routes are changed into server goto.
- When loading a new game in an old server, patrol and goto routes are lost.
