Fix filtering in area command filter + add tech level filtering

[przystuj]

Fix

Recent tweak to this widget made it always target allies (so you could very easily reclaim allied buildings by accident).
I refactored it so that:

Always filter units by target teamId. For enemies use ENEMY_UNITS (so all enemy teams).
alt - filter by unitDefId and teamId
ctrl - filter by teamId. When targeting wreck, filter by techLevel

New feature

Holding Ctrl when targeting wrecks will filter by tech level. So now you can resurrect/reclaim only t2 units, etc

Test steps

• Check if modifiers work as expected for various commands
• Check if tech level filtering works as expected

Reclaim will no longer target allies, regardless of modifiers.
I also disabled loading allied units when Ctrl is held. You already can load them with regular area load command.

Apparently we don't want this behaviour. Now it's:

Always filter units by target teamId. For enemies use ENEMY_UNITS (so all enemy teams).
alt - filter by unitDefId and teamId
ctrl - filter by teamId. When targeting wreck, filter by techLevel

Handled the comments + added a command limit, like in smart area reclaim

Code looks good, modifier design is for somebody else to decide.
