dependency inject/singleton the ban and repo systems

[chen-chan1]

i want to be able to swap them out. in the future when i get my own hardware in a data center. i can pick the best. even the file handler as i want to eventually swap it with something my gpu can chew its ass out with.

its best to dependency inject and singleton as much stuff as possible to not deal with the overhead that is modules witch i predict to be slow.
