Add separate patches

[hhyyrylainen]

Each species should have a per patch population and they need to try to move surrounding patches at some intervals.
The patches should have different properties like compound densities, light levels, and background image etc.

It's fine to be fixed at first: #682

[hhyyrylainen]

Per the balance comment: some patches should be harder to play in than others.

I assume this also means that this depends on: #684

Light and Heat can be done as environmental compounds for now i think (like how we do dissolved oxygen and c02)

[Untrustedlife]

Maybe we can get a thermoplast in for this release

[crodnu]

thermoplasts arent just chloroplasts but with heat, they only work by moving through a heat gradient (either from hot to cold or the other way around idk)

[Untrustedlife]

Yeah thats a good point. It would have to only run when teh cell is moving i guess? Hmm

[Untrustedlife]

I will tackle this finally
