Adding support for content mods

As mentioned in #332 CM currently breaks upon finding an unknown object/upgrade/achievement.
By adding

if (you == undefined) {
   CM.Sim.InitData();
}

CM will now re-initialize the "database" of objects, upgrades and achievements.
This will still produce an initial error in the console, but will then be resolved.

Furthermore, as noticed by @staticvariablejames we currently called CM.Sim.CopyData with every loop.
This call has been moved outside of the loop.

I'll repeat what I said in Issue #332. CM.Sim.CopyData is inside the loop for a good reason. Unless you undo the changes afterward, the calculation for each building afterward is incorrect. Unless I missed something. Please take a look closely.

For example. me.amount += amount; is called on each object once. The data is not reset after an iteration of the for loop. This means for every building calculation afterwards, there is an extra building added.

Another example: CM.Sim.Win('Click'); (or any other CM.Sim.Win()) is called. That achievement has to be removed for the next iteration or else an extra achievement is there incorrectly.

You are indeed correct. I'm sorry I was too quick to judge.
With #338 I have resolved the problem.

That's okay. Everyone makes mistakes. If you have a question as to why I did something, don't hesitate to ask! I only by chance noticed this one. I sure didn't go through everything.

Besides this edit we have not really changed anything in the way the calculations work, so all should be fine :)

I was going to add that another reason why I also take a long time is because everything is kind of delicate. Almost everything is in a certain order for a reason. It's good to know nothing else has been changed much. I did notice some change to CalculateGains and that is also a delicate area. Do be careful =).
