Feature Request: Remove the Need to Manually Install Hugo

[frastlin]

Hello,
Please remove the need for a human to install Hugo. If they have it, it's fine, but if they don't, Cupper should install it.
A fantastic way of doing this is through:
hugo-cli
If this is added to a dependencies section in the package.json file, npm install will install the above package, and the first time one runs:

"npm run serve"

Hugo will properly be installed if it is not already.
