[Suggestions][0.254b] a little bit tweak

[Kender]

(game version 0.254b)

1. Allowing x2, x3 game speed during battle.
One of the good features in 0.254b is that the game speed return to 1x, so we can direct the fight better. I just have only two things to point out.
first, the game speed cannot be changed during battle, it is forbidden. Sometime it is better to fast forward some combat if the out come is clear, such us fighting a mad squirrel. Do we really need to watch the slow motion every time?
second, game speed is still fixed at 1x after the battle for a few second (5 sec). Maybe it is just me, but once out of battle, I always have a lot of repair, hauling, firefighting want to be done fast. Slow motion does not help.

2. Focus fire by a group of colonists back
This feature was in previous build (I remember it was in 0.232). Player can select several colonists and right click on an enemy to focus fire, but now it is replaced by a 'move' order. Considering the accuracy of my shooters, I think focus fire is a more effective way to eliminate a specific target rather than spread my fire power randomly to all enemies.
It would be much easier if we got the old feature back.
