Reverse minefield deployment

[cheatereater]

Currently, offensive minefields laid just before a scenario seem to be placed between the combat area and the enemy's bases, like so:

Here, in a destroyer action, versus Germany and Britain, the British minefields are placed between the ships and the German bases, while the German minefields are placed between the ships and the British bases. IMO there are two main problems with this:

1. This implies that the warships went out towards the enemy bases, laid mines, then came back, and then went out again to start combat. Their initial paths are clearly from friendly base->enemies, so they went friendly base->towards enemy base->lay mines->towards friendly base->towards enemy base->combat. It seems a little nonsensical, and it would imply that the minelayers are crossing each others' paths while laying mines and then on the way back. Do they wave hello as they pass?

2. This makes mines an offensive weapon that hurts a losing enemy: the enemy that is retreating towards their base is retreating into a hazardous minefield. This is not how mines are normally used in combat, as they take a more defensive role: mines are laid in areas you control and can chart them to hinder enemy movements and give you a safe place to move, as is done by harbors and coastal guns.
*edit* I also thought of the fact that it implies each set of ships crossed through an enemy minefield to reach the combat! That wouldn't be right...

The mine field locations should be flipped, so that friendly mines are laid in your path of retreat, and enemy mines towards their base. This solves both problems:

1. This makes more sense, as warships will go straight from friendly base->lay mines->combat, and the minelayers are working in safer areas near their own base.

2. This makes mines a defensive weapon in-line with their other uses. A player who invests in minefields can safely retreat towards their mines, hoping that the enemy could stumble into them, and this also works with a doctrine that relies on lighter forces (who make up the minelayers). A player who wants to chase a retreating enemy may be more cautious if they know the enemy routinely lays mines and they don't have enough minesweepers to mark safe areas or light forces to screen their capitals.

Note that more offensive uses for mines are already nicely captured in the strategic layer, where ships sometimes hit mines. This better represents the offensive mine uses, such as drifting mines into shipping lanes or laying mines near harbors, but these are not combat-related.
