* Add support for storing DM history between users in a SQLite3 database.
* Opt-in by editing your settings.toml to set DirectMessageHistory/Enabled=true
* Retention days (default 90) will flush old DMs on app startup.
* On the front-end, DM history is checked when a DM thread is opened.
Spin out components for:
* MessageBox: draw a chat message in the chat history panel as well as reused
in the Report Modal.
* WhoListRow: provides a consistent UX for the Who List and Watching tab. On
the Watching tab, the video button is replaced with the boot from video.
Other changes:
* Move VideoFlag into its own separate ES module.
* Emoji available reactions are moved into MessageBox.
* On WhoListRow: usernames are clickable to also open their profile page.
* On WhoListRow: the Watching tab is now sortable and follows the user's
sort selection like the Online tab does.
Move some chat modals into external components:
* LoginModal
* ExplicitOpenModal
* ReportModal
* The Photo Modal was hoisted into the main index.html page, because it is not
a Vue component and relied on global onclick handlers and the DOM.
Spin off some external JS modules:
* isAppleWebkit moved to lib/browsers.js
* Local Storage management centralized and moved to lib/LocalStorage.js
