Inf doc Tec Tree suggestion and M10

[Warhawks97]

The armor doc has currently M10 right at default. Since AB got hellcat as unlock i would suggest to make M10 simply as standard 0 CP allied TD such as axis have marders and stugs.

The inf doc VT abiliy is the worst of all in game having very short activation range and activating only howitzers. Axis Def doc here is by far more powerfull having much more VT activation range that also activates all arty pieces (grille, 88, 105).

Suggesting: M10 Wolverine as standard 0 CP US TD. The free slot in inf doc can then be used for VT unlock. VT would then cost 2 CP, activation cost from 50 to 75 ammo and activation range increased to 100. VT activates then 105 sherman as well and available not only for spotters but also for the captain.

- M10 unlock replaced with VT unlock. M10 for 0 CP in all US docs.
- VT cost increased from 50 to 75 ammo.
- Activation range increased to 100 (all axis VT´s have arround 100 and more range)
- VT added to Captain as well (all other VT´s in other factions can also be used by officers)
- VT activates 105 sherman as well and 105 howitzers. Maybe even also the 75 mm pack howitzer.
