as mentioned in https://github.com/dani-garcia/bitwarden_rs/issues/223

Added infos about enabling https when softwares getting certs are using symlinks

Added SMTP_FROM config to examples and made it mandatory, it doesn't make much sense to not specify the from address.

Using the room ID instead of an alias isn't supposed to be working for joining rooms, and doesn't work when joining over federation. It only works when your server is already participating in the room.

I changed the way bitwarden_rs is packaged (the web interface is now an addon-package instead of bundled) and added a 'stable' package which follows recent releases.
 I assume that following releases instead of the master branch is encouraged so I removed the link to the (still existing) bitwarden_rs-git package which does the latter.

Hi!
I made two packages for Archlinux, one for the purists (without web interface) and one with the web interface and wanted to link to them here.
I'm not sure if that is the best position to advertise this, let me know if you think the links are better put elsewhere.

Apart from that: If you have any other suggestions/remarks for repackaging, please tell me. 

Currently I'm linking to the latest master commit, but I would really welcome it if you could make a release every now and then.
Thanks for your great work!

Updated dependencies and created 'rust-toolchain', to mark a working nightly to rustup users, and hopefully avoid some nightly breakage.
