add "counters" metadata to each strategy as they are discovered

[MetaMemoryT]

This data would become useful for someone trying to build a general ai that reacts.

For example, BM_Library very frequently beats DoubleMilitia so we would add a property to BM_Library as such:

counters: ['DoubleMilitia']

This information is useful to an experimenter trying to get ideas, just browsing and running the strategies.

This information may not be immediately used by this project, but could become useful to other projects.

Since everything counters SillyAI no need to mention what counters SillyAI.

This issue could be closed when at least half the strategies have recognized counters.

The counters list could be ordered in most significant counters to less significant.

What exactly defines an AI that definitely beats another? Plus, shouldn't there be some other metadata like "this AI counters this strat on average about x% amount of the time"?

However, I will also begin running simulations and anything that successfully "a clear winner is defined" on the web page will be marked as a counters.
