Resume suggestions should be shell escaped

[derekslager]

Run a task with a configuration requiring shell quoting, as below:

$ lein monolith each sometask '{:config-option ["foobar"]}'

If an error is encountered, the plugin emits a message like the following:

Resume with: lein monolith each :start subproject sometask {:config-option ["foobar"]}

The message is quite helpful, but it requires manual shell quoting if you copy and paste. Ideal behavior would be for the printed representation to be properly escaped.
