Title: Added command to check if a dependency is already installed

As I use the tool with provisioning and don't want to wait every time for all `gem install` to run through, I added a n option to the `backup dependencies` command, making it possible to check if a dependency is already installed using `backup dependencies --installed `. It simply wraps the `gem list -i -v 'version' 'name'` command.
