change high tech mocde to level 5 instead of 10

[benben10]

vudu- your tank level, troops (tech) level and money level are all different in a normal game. it should never happen that you have only made it to level 10 tank with 10k tank value and level 10 troops all at the same time in a normal game. so therefore having a game start with 10k money and level 10 tank and level 10 troops would be unbalanced. and if we ignore the money, like you said by 40-50 mins into the games (when troops/creeps) you should be way past level 10. so high tech mode is not balanced.
