Every listmonk instance scans the DB periodically to look for
running campaigns to process. This made running multiple instances of
listmonk impractical as they would all pick up the same running
campaign and process them, resulting in duplicate e-mails.
This commit adds a `--passive` flag to the binary that runs listmonk
in a "passive" mode where campaign processing is disabled. This allows
multiple instances of listmonk to be run to handle different kinds of
requests if there is a requirement (scale/traffic?). It is important
to note that there should only be one non-passive instance running at
any given time. If distributed campaign processing is ever considered,
this will change.
If `<!doctype html>` is not found in static/email-templates/base.html,
all system e-mail templates are assumed to be plaintext and go out
as content-type: plaintext e-mails. With this, all HTML tags can
be stripped out of the system e-mail templates (while maintaining
Go template tags and logic) to have plaintext system e-mail templates.

- Introduce `main.appDir` and `main.fronendDir` Go compile-time flags
to hardcode custom paths for loading frontend assets
(frontend/dist/frontend in the repo after build) and app assets
(queries.sql, schema.sql, config.toml.sample) in environments where
embedding files in the binary is not feasible.
These default to CWD unless explicitly set during compilation.
- Fix the Vue favicon path oddity by copying the icon into the built
frontend dir in the `make-frontend` step.
The new `--i18n-dir` directory allows the loading of an external
directory of i18n JSON files, milar to have `--static-dir`
works. New languages can be added and existing language files
can be customized this way.
This commit changes file loading behaviour so that invalid or
non-existent don't halt the execution of the app completely but
merely throw a warning and continue with the default (en) lang.
This is a major feature that builds upon the `Messenger` interface
that has been in listmonk since its inception (with SMTP as the only
messenger). This commit introduces a new Messenger implementation, an
HTTP "postback", that can post campaign messages as a standard JSON
payload to arbitrary HTTP servers. These servers can in turn push them
to FCM, SMS, or any or any such upstream, enabling listmonk to be a
generic campaign messenger for any type of communication, not just
e-mails.
Postback HTTP endpoints can be defined in settings and they can be
selected on campaigns.
- A check for new versions on the GitHub releases pages happens
once every 24 hours. When a new version is available, a notice
is displayed on the admin UI.
