evolve: mechanism to load some commands selectively
This patch introduces a new config option: experimental.evolutioncommands to
load evolve's command selectively.
It is part of a sequence of patches to make evolve's command respect the value
of experimental.evolution. Once these commands are ready and actually respect
the flag, they are safe to use and can be enabled with the mechanism developed
in this patch.
