`notification.status` may not be present, e.g. follow notification.

That way, they are displayed in a list below the corresponding toot.

add <div.zoomable-image__margin/> to keep margin of the image on zooming
move setting `scrollLeft` and `scrollTop` of container from callback of
`setState` to `componentDidUpdate`
add 'hammerjs' package for touch gesture detection
rewrite `ZoomableImage` using 'hammerjs'

max_id in the fetch request should be a status id, but media attachment id was used.

`Response.prototype.clone()` must be called before the response used.

This fixes an error from ServiceWorker and failing to load image when the
image is not cached.

This patch adds null item (i.e. gap) handling on below functions to avoid TypeError.

* `filterNotifications` called on user mute/block
* `deleteByStatus` called on status deletion

Comparison was downcasing only one side, therefore if previously
existing account had a non-lowercase spelling, it would be ignored
when checking for duplicates.

New rake task `mastodon:maintenance:find_duplicate_usernames` will
help find constraint violations that might have occured from the
presence of this bug.

Bump version to 2.3.3

to_s method of HTTP::Response keeps blocking while it receives the whole
content, no matter how it is big. This means it may waste time to receive
unacceptably large files. It may also consume memory and disk in the
process. This solves the inefficency by checking response length while
receiving.

* Refactoring scss

introduce scss variables for the media modal
fix css block structure corresponding to react components
fix flex layouts
remove background image of the loaded image on the media modal

* Fix typo

* Fix stack overflow on importFetchedAccounts

  When the account has moved property, it should process destination
  account instead of source account itself.

* Set account id instead of account object for moved property

  This restores "foo has moved to" indication on account view, and
  fixes `reblog` index on `accounts` object store.

* Invites: Add '1 week' as expire option

IMO a max. of 1 day is too short. Not everyone has the time and motivation to use an invite in a 24 hour period. 1 week as a max. is I think a good compromise between convenience and security.

* Update en.yml

HTTP connections must be explicitly closed in many cases, and letting
perform method close connections makes its callers less redundant and
prevent them from forgetting to close connections.

Fix performance regression from #6836

Usernames with dots in them do not work with routes, because the dot usually separates the desired page format (e.g. json). I don't want to mess with changing route constraints for this patch release.

* Permit dots in usernames with conditions

- Dot cannot be the start or end of username
- a.lice and al.ice are considered the same during sign-up

* Fix regex mixin flags

See also: #6837, #6667

* request: in the event of failure, try other IPs (#6761)

In the case where a name has multiple A/AAAA records, we should
try subsequent records instead of immediately failing when we have a
failure on the first IP address.

This significantly improves delivery success when there are network
connectivity problems affecting only IPv4 or IPv6.

* fix method call style

* request_spec: adjust test case to use Addrinfo

* request: Request/open: move private addr check to within begin/rescue

* request_spec: add case to test failover, fix exception check

* Double Addrinfo.foreach so that it correctly yields instances

Up until now, the order seemed to be in the *opposite* order,
which caused the WebUI to populate mentions in reversed order
when replying to toots local to one's instance.

* update to new version of devise_pam_authenticatable2

* fix behaviour if suffix is nil, fix environment loading, fix user email creation

* code cleanup/fix linter warning

In Devise::Mailer#email_changed, the new email might be in the email attr.

Fix #6821

Display summary of attachments in description, and mark up content
warning if present, e.g.:

    Attached: 3 images · Content warning: Dota 2

When text is not supposed to be hidden, it looks more like:

    Attached: 3 images

    Here is the text of the toot

With #6817, multilinguagility should be assured...

Fix #6784

pretty quick fix, and with the 1 week expiration i don't think we need to be too worried about the existing files

closes #6798

This will prevent, for example, `rake mastodon:redownload_avatars` from crashing when an instance is no longer responding to connection attempts, instead silently continuing as expected.

Apply "margin: 0 auto;" at line 443 to fix issue #6787

This is the first step to make Mastodon work offline. It is also required
by Chromium to trigger Web Manifest automated install prompt.
