Assert cleanup

[joseasoler]

Now that it is possible to compile Assert targets, it would be desirable to release beta versions of ExtraModMod with asserts enabled. In order to do this, all "fake" asserts need to be cleaned from the DLL first.

Asserts reported but not fixed yet in ExtraModMod:

https://sourceforge.net/p/tholalsffhaimod/bugs/218/

Asserts not reported nor fixed:

Assert Failed File: CvGameTextMgr.cpp Line: 20659 Expression: (iBaseModifier* iBaseProduction) / 100 == city.getYieldRate(eYieldType) Message: Yield Modifier in setProductionHelp does not agree with actual value

The version has been removed as this issue will be a WIP for a long time.
