1) Allow modification of flag metadata by middleware functions (coreybutler)
(SHA: 33586e0cf809023b79d24e98ef0eada431a54b90)

1) Added middleware capable of being applied to all commands _except_ a given list of commands (cherry picking). Also added a special _ignore_ parameter to the commonflag (universal flags) configuration, allowing applications to be applied to a filtered set of commands/subcommands. This closes #3 and it closes #4. (coreybutler)
