feat: Hat Tip Mode

[refcell]

Description

Find a cool directory structure you like, such as amble itself?

This mode should enable amble to pull down a specified github repo and try to build a similar structure using it's components.

This may require refactoring of core amble modules and commit-execute scheme to allow for changes to dynamically be "rolled back" if needed.

This would be called hat tip mode and should also provide a hat tip at the bottom of the generated readme.
