Rebalance some civ and team bonus.

Two nerfs to ptol bonus: easier capture, and +50% build time (see
https://wildfiregames.com/forum/topic/83784-introducing-the-official-community-mod-for-alpha-26/page/7/).
An update to four team bonuses that were rather lacking in A26 and
previously.
- Athens is now CC techs -50% research time and -30% cost.
- Seleucids 20% cost discount for CCs also applies to build time.
- Persia team bonus is cheaper, faster building barracks and stables.
- Carthage is infantry mercenaries -50% train time.
