While debugging the donation stuff, ran into a more general problem involving 
how merit was passed from parent to offspring. It appears that there has 
been a problem there for a while now (over a year at least), which does 
alter the way a run would proceed. Fixed it. 

Because organisms fitness is usually calculated only on divide, it does not 
take into account the changes in organisms merit due to donations. Thus, 
I added another variable to organisms phenotype, life_fitness, which is 
updated every time when the merit is updated during organisms lifetime. 

Added another method to the compete_demes event which allows selecting for
demes based on their average life_fitness. 

Added two more output events, dump_donor_grid and dump_receiver_grid, which 
dump a grid of 0s and 1s for organisms who have donated/received merit. If
the cell is empty, -1 is outputted.
