System notifications

By default, features considered as ones that can take a long time, will send a system UI notification if they do take long. Unless you're on Do Not Disturb or something, they should sound - which is the point of it. They're sent so you can safely move away from the terminal and know when we're done, so you can get back to whatever's next as soon as possible.

We currently enable this for the following features:

• clean (on finish)
• build (on finish)
• migrate (on finish)
• kickstart (on finish)
• clean (on error; remember errors don't stop execution here)

On finish notifications are fired if the running task took more than 30 seconds to complete. This threshold can be disabled, so they're shown even if it takes 1 second. In future versions you'll be able to customize the threshold.

Notifications are enabled by default, but can be disabled if you don't like them.

Warning

On Linux, it's assumed that notify-send is installed. If not, notifications simply won't be sent, without a warning.
