Add back Ostheer command P4, Puma and ACE self-repair

Accumulative bug fixes (as a result of official updates)

Make conscripts able to use AT nades again

Making British forward observation assembly point not mutually exclusive with medics upgrade; now its artillery cover reverted to original

Brits mortar pit price reduced to live version, 350mp

Tiger ACE now has the full set of abilities

Trenches can now be built in any territory

Raketen price is tuned down to match original 4 men squad

I hope this fix resolves the issues that in the revamped tech tree many units are not showing up, it was a long-time problem

Now conscripts can upgrade to 7 men, but in this mod this allowance must be researched in Tier3, and locks out weapon upgrades
