[wip] bridge python and c# and bring in rank torrent name (#177)

* [wip] bridge python and c# and bring in rank torrent name

* Container restores package now

Includes two dev scripts to install the python packages locally for debugging purposes.

* Introduce slightly turned title matching scoring, by making it length aware

this should help with sequels such as Terminator 2, vs Terminator etc

* Version bump

Also fixes postgres healthcheck so that it utilises the user from the stack.env file
