Increased Imperial Resources and Budgetary Changes

[szurkey]

Currently, the only reason for Imperial player to upgrade Outposts to
Worlds is to increase the effectiveness of Planetary Defense Systems
that he may have there and to increase the free maintenance available
in that system. To give the Imperial player more incentive to upgrade
Outposts to Worlds, increase the income of connected Imperial Worlds to
4, unconnected Worlds to 2, and the provincial capital at Gashidda to 6
if connected and 3 if unconnected (impossible if not playing on an
expanded map). Decrease the income of unconnected Terran Worlds to 4,
and increase the income of Sol to 12. To balance out the much higher
income of the Imperial player, change the Imperial of budget from +10
Resources subsidy to -8 Resource tax.
