misc refactoring (#140)

* add self host params

* add random port for main

* and so the crazy refactoring process sees the sunlight after some months in the dark!

* Too lazy to write descriptive message

* better ignores

* Fixed what was broken.

* bad things happen when you forget about that one little change you made ages ago

* I'm sorry.

* Reset error count between rows. herpderp

* squash me

* I am sorry

* add keys command
