colored gem is old and broken, maybe use colorize?

After running bundle update I get an issue with the colored gem:

SSHKit::Runner::ExecuteError: Exception while executing as moi@ec2-magicnumber.us-west-2.compute.amazonaws.com: no implicit conversion of Hash into String
/usr/local/rvm/gems/ruby-2.1.2@moi/gems/colored-1.2/lib/colored.rb:70:in `colorize'
/usr/local/rvm/gems/ruby-2.1.2@moi/gems/sshkit-1.6.1/lib/sshkit/color.rb:7:in `black'

It seems colored and colorized do kinda the same thing and now seem to be clashing.
The colored gem hasn't been updated in 5 years and doesn't allow issues to be made on the Github repo. Using colorize should be better, they do update regularly and do allow issues to be reported.

I can confirm that colored and the latest (0.7.5) version of colorize are clashing, I reverted to using colorized 0.7.4 and boom, everything works again!

Still, might be good to change to colorize gem.

I do reproduce this (thanks @Tomtomgo for the version to downgrade to). I second your thought on changing to colorize gem.

I agree; I think the choice to use colored was a bad move when I originally wrote the gem.

If you've got time, a PR would be welcomed. If not, I'll get to it next week as I lack the bandwidth to do this now.
