【GS】Canal Enhancements

Since the orignal Canal district in GS is so useless, this mod enhances the canal for a little bit so it could be an real useful district for playing the game. What this mod does: 1、Changing the cost for the Canal to a normal cost for a district (So it would be the same cost with other districts like the Campus.) 2、Commercial Hub gets +2 Gold bonus for adjacent Canal tiles. 3、City with a Canal has a 50% Production bouns towards the Trader unit. 4、+3 Food bonus for a Domestic trade route if the Destinatiton city has a Canal. 5、+2 Production bonus for an International trade route if the Destinatiton city has a Canal. 6、+2 Gold bonus for any trade route if the original city has a Canal. 7、Double the Gold bouns for any trade route if it passes through a Canal.(This is in the original GS, but I think it is worth mentioning.) 8、Builders can spend their charges to complete 10% of the original Canal cost.
