Add Miniflux script (#935)

* Add Miniflux script

* Delete ct/headers/miniflux

This will get auto-generated by our func

* Minor fixes to Miniflux scripts

- run `apt update` before `apt upgrade miniflux`
- use selfh.st/icons for logo
- remove `[trusted=yes]` from miniflux source
- remove extra spaces
- change `apt-get` to `apt`

* Move Miniflux DB creds

Move Miniflux database credentials from a separate file, to directly inside of the `/etc/minflux.conf` file.

* Update Miniflux source to be trusted automatically

* Store ~/.pgpass for db backups using pg_dump

* Use GitHub Release binary instead of UNSIGNED apt source

* Add apt -y clean

* Make recommended changes

* Added notes

* Set `LISTEN_ADDR=0.0.0.0:8080` by default

* Finishing touches. Removed some unneeded msg blocks
