Make convoys follow player orders

[nightraven1901]

As title.

Start them on the same conditions as they do now, retreating, but let me over-ride the frankly idiotic task force system. I'd also prefer if every ship was in its own division, to help minimise the almost deliberate ramming and torpedo eating they insist on doing that I could save them from. Do not ever, give a player a defence target that can't perform basic operations, it's poor game design. If a player doesn't want to control them, this won't cause them the slightest hassle at all.If they do it'll cut frustration by a massive amount.
