1.6.3g update

Hey there folks-

The latest public build includes significant balance updates and starter-city adjustments for a number of campaign missions, and also a substantial re-balancing of the tax system (low-level housing now gives much less in tax, so you'll need to lean more on exports in the early game.)

You can check out the changes log in the menu-screen for full details- bunch of other minor improvements and fixes have gone in.

Thanks, PG
