Make --quiet a global flag / flag supported by all commands

[jabbrwcky]

Hi,

it would be nice to have the --quiet flag for all subcommands. I currently use gem bump in a filter script for git-flow and it is a real pain to catch all output by gem bump to make sure that the filter just returns the version to use for the release.

Thanks for the report, @jabbrwcky , and sorry for not following up on this earlier.

I believe your issue should be addressed in 2.0.0.pre.1, see #64

Specifically, there's now more flexibility in configuring gem-release. And things are tested better. See https://github.com/svenfuchs/gem-release/tree/sf-v2#configuration for configuration options.

I believe in your case it should be sufficient to use:

# top level keys, apply to all commands
quiet: true

or

export GEM_RELEASE_QUIET=true

I am going to close this here. Please let me know if things do not work as expected.
