conf/shortcuts: implement a key to command mapping

Permits users to map keys in their configuration file to an array of meli commands

e.g:
[shortcuts.listing]
commands = [ { command = [ "tag remove trash", "flag unset trash" ], shortcut = "D" },
             { command = [ "tag add trash", "flag set trash" ], shortcut = "d" } ]
