Add silent flag to the cli command to supress game logs (#46)

[xaviserrag]

Modified the CLI project to accept a --silent value so the gameplay skips the play logs.

Had to use -m (mute) for the short version of the command since -s was already used, open to suggestions on using other options.

Saw this project yesterday and I loved it, keep up the good work! ;)

Closes #46

@xaviserrag Also, if you can add tests to this to at least preserve the coverage, that'd be awesome!

@xaviserrag Just writing to let you know that --skip (and -s) where removed in favor of --yes (#93). -s is now available for you to use with --silent.

[xaviserrag]

Sounds good! Will go through the changes soon!

@xaviserrag I just noticed that the documentation needs to be updated as well (it lists the options in alphabetical order).

Thanks!
