* Configure webpack to poll for changes in development

Vagrant on Linux/macOS hosts shared files via NFS, which doens't
support inotify-based watching of files. This tweak makes webpack
check for changes every second, and rebuild if necessary. This
removes the need to restart Foreman every time a frontend file
changes. Note that rebuilding is still a relatively lengthy
process.

The polling frequency can be changed to taste.

* Only poll in Vagrant

This tests for the presence of the VAGRANT environment variable to
determine whether or not we're in Vagrant. It is set in .env.vagrant,
which is set up to be included in the Vagrantfile.

sessions overview, authorized followers page, account deletion page.

* Fix #117 - Add ability to specify alternative text for media attachments

- POST /api/v1/media accepts `description` straight away
- PUT /api/v1/media/:id to update `description` (only for unattached ones)
- Serialized as `name` of Document object in ActivityPub
- Uploads form adjusted for better performance and description input

* Add tests

* Change undo button blend mode to difference

Call to warden.authenticate! in resource_owner_from_credentials would
make the request redirect to sign-in path, which is a bad response for
apps. Now bad credentials just return nil, which leads to HTTP 401
from Doorkeeper. Also, accounts with enabled 2FA cannot be logged into
this way.
