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.
