Title: Add screen notification when custom callbacks are added

When defining a custom callback like so:

```
Paratrooper::Deploy.new('amazing-app') do |deploy|
deploy.add_callback(:before_setup) do
# code to disable new relic
end
end
```

There should be the ability to add in a screen notification of what is
happening.

Maybe something like:

```
Paratrooper::Deploy.new('amazing-app') do |deploy|
deploy.add_callback(:before_setup) do
deploy.add_screen_notification("Disabling newrelic ping")
# code to disable new relic
end
end
```

Thoughts?
