Dispersal weight

[rafaqz]

Adding a weight parameter/scalar to DispersalKernel would allow multiplying a size-structured population by a weights vector prior to dispersal to simulate size specific dispersal patterns. As it's a parameter, it could also come from a Grid or Aux to use heterogeneous dispersal based on local conditions, for mixed or sized structure populations. Or whatever.

But I think it would be useful. The default value would be nothing, which wouldn't have any overhead.
