If a realm is configured to allow any user to upload a realm emoji
then that user should also be allowed to delete the emoji in case
he feels it doesn't look good or if he uploaded a wrong emoji file.
This commit tweaks the realm emoji settings UI to allow an user who
uploaded an emoji to delete it.
Fixes: #4761.
- Add file_name field to `RealmEmoji` model and migration.
- Add emoji upload supporting to Upload backends.
- Add uploaded file processing to emoji views.
- Use emoji source url as based for display url.
- Change emoji form for image uploading.
- Fix back-end tests.
- Fix front-end tests.
- Add tests for emoji uploading.
Fixes#1134
This changes the layout of administration for non-administrators such
that they can view organization settings and emoji settings and
displays everything as readonly unless they have the capability to edit.
For now, we just enabled this for the emoji settings and organization
settings features.
This restructures the styling for the Zulip settings and
administration pages to minimize use of Bootstrap and use a consistent
styling library for similar elements.
While it is basically a wash in terms of the page's visuals, it will
make our life a lot easier for future work on improving the settings
pages section of the site.
