New:

• Created CustomActivity activity indicator type. this lets you easily create custom activity indicators with a series of characters that are looped over for the animation.
• Added a customActivity method to the Console protocol, which initializes a new CustomActivity instance.

let indicator = context.console.customActivity(frames: ["⠋","⠙","⠹","⠸","⠼","⠴","⠦","⠧","⠇","⠏"])
_ = try indicator.start(on: context.container)
// Do something that takes a long time.
indicator.succeed()

Only logs command help when there are errors in command usage, no longer logs errors in the command execution.

Fixed:

• Fixes an issue where ephemeral messages would not clear correctly. (#80)

Fixed:

• Eliminate Swift 4.1 deprecation warnings.

New:

• -e short flag now supported for setting environment.
