Better Splashes 2016-10-05

This mod changes the Wonder splash for Parthenon and Porcelain Tower, the Era splash for the industrial Era, the Background for UN Congress (BNW)
What were the mistakes of the original ones?
Parthenon: Romans instead of Greeks
Porcelain Tower: Japanese-style pagoda not matching the Chinese style (and correct one) 3D model
Industrial Era: Statue of Liberty makes splash not so universal
UN Congress: original background give no majesty to UN, nor represents the high number of delegates.
