Add Snapcraft metadata and install/maintenance hooks (#666)

* Add Snapcraft metadata and install/maintenance hooks

* Move set-environment script into snap/local

* snap: Remove diesel-cli part.

This *was* necessary as of 0.3.0, but now `plm migrations run` does the job.

* snap: Add an actual description

* snap: Add an 'enabled' config item.

Don't try to run until enabled is set, and automatically run the
migrations when we are enabled

summary: Multi-user blogging platform, federated over ActivityPub
description: |
Plume is a federated blogging platform, featuring:
* A blog-centric approach: you can create as much blogs as you want with your account, to keep your different publications separated.
* Media management: you can upload pictures to illustrate your articles, but also audio files if you host a podcast, and manage them all from Plume.
* Federation: Plume is part of a network of interconnected websites called the Fediverse. Each of these websites (often called instances) have their own rules and thematics, but they can all communicate with each other.
* Collaborative writing: invite other people to your blogs, and write articles together.
