The like button previously didn't have a title for anonymous users,
because the `canToggleLike` flag wasn't set, but the `liked` flag wasn't
set either. This made the button inaccessible to blind users.
This is how `loadScript(url)` currently deals with multiple concurrent requests
1. Check existing `<script>` tags, and mark existing scripts (other than the
input `url`) as loaded
2. Find "true" `url` of the requested resource (CDN, subfolder path, etc)
3. Check if we have loaded the resource with that "true" `url`, and resolve
immediately if we have
4. Otherwise insert a `<script>` tag with the "true" `url` to load it
For example, in a subfolder install:
- Input `url` = `/javascripts/script.js`
- "True" `url` = `/subfolder/javascript/script.js`
And the _very_ subtle bug here is that we should use also use the true `url`
for step (1), because:
- Since the input and true `url` are different, we mistakenly mark the true
`url` as loaded in step one
- After finding the true `url`, and setting `loaded[trueUrl] = true` in (1), we
resolve the promise prematurely, when the resource could still be loading

- By default, behaviour is not changed: tags are made lowercase upon creation and edit.
- If force_lowercase_tags is disabled, then mixed case tags are allowed.
- Tags must remain case-insensitively unique. This is enforced by ActiveRecord and Postgres.
- A migration is added to provide a `UNIQUE` index on `lower(name)`. Migration includes a safety to correct any current tags that do not meet the criteria.
- A `where_name` scope is added to `models/tag.rb`, to allow easy case-insensitive lookups. This is used instead of `Tag.where(name: "blah")`.
- URLs remain lowercase. Mixed case URLs are functional, but have the lowercase equivalent as the canonical.
* FIX: keep files in order when adding multiple uploads
* use filename in the placeholder when uploading files
* add tests
* add consecutive nr to the placeholder when multiple uploads with the same filename
