Add a command to generate a task template file

[zipplet]

At the moment, the task template needs to be manually maintained when new settings (features usually) are added - and the user might accidentally delete it or use it as their real task settings file rather than copying and modifying it.

godaemon should have the ability to generate a task template file based on the settings it understands, along with comments to go with them.

This issue sort of goes hand-in-hand with godaemon having an "installer" that would ask godaemon to generate a sample template file for you by default.
