Please move "Fuzzy matching of subcommands" into hammer core

[ares]

I ❤️ it

few observations:

it seems the fuzzy matching does not work with aliases, e.g.

hammer ro s --id 1 # does not work
hammer ro show --id 1 # works
hammer ro i --id 2 # works

and as we discussed, it would be nicer if hammer -r would not print

Error: No such sub-command 'r'

but rather all possible commands.
