* 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.
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
This commit makes an initial port of the front-end over to a proper Vue
CLI application. It seems to work from surface level testing.
Changes made:
* Rename web/static to public/static to place it into the Vue build path
* Notes: web/static/js/BareRTC.js and web/templates/chat.html are now
deprecated
* Rename web/static/js/sounds.js into src/lib/sounds.js making it a
proper JavaScript module with exports.
* Fill out initial src/App.vue by copying and updating
web/templates/chat.html and web/static/js/BareRTC.js into this module.
