Global speed of units can be tweak by changing only one value.
Balance will be easier.
Some intermediates values are used for making balance easier.
That patch does not change walking value (I didn't care of Run value). There could be slight changes due to rounding and I merge support units whose values were between 8.5 and 9.5.
(When that will be done also for Vision, we could do that Vision thing).
Things can be done in another way (I already wrote 3 different patches...)
I let some 1.0 for the one who will try to make values consistent or do some balance.
