even if the global configuration is to disallow it.
* When parsing, include all media URLs, not just the ones from allowed domains.
That makes it possible to change allowed domains on-the-fly,
while still allowing media in individual messages to be shown manually
(via the message actions dropdown).
* Merge `embed_audio`, `embed_video` and `show_images_inline` into `render_media`
* Create new config settings for allowable domains for images, video and audio
* Check the URL domain against a whitelist for the message actions dropdown
Instead of on the views/components.
We still have `close` methods on the components, but they are just
event handlers and not external API methods to be called by other code.
Instead `close` should be called on the model.
This is largely a leftover from the Backbone.View days and makes less
sense now that the UI is componentized.
Ideally we don't want to call commands on the "views themselves, instead
we should be working on the the models and let the "views" update
themselves automatically.
Also, given that the `jid` attribute on the chat views might change,
especially when rendered declaratively in other frameworks like React,
a view might not be available at times where we previously might have
expected it to be (since it's been repurposed for a different JID).
The eventual goal is to avoid UI-related stanza processing if the relevant chats
aren't in the DOM.
With the current architecture, chatboxes are created (and the stanzas
related to them processed) even if `#conversejs` isn't in the DOM.
* Initial work on making controlbox an element
* Create a shared base class
* Ceate ChatBoxViews proxy
* Update sass now that certain classes are moved to converse-chats element
