Markus Schirp 41d9700473 Refactor runer infrastructure
* Nuke around 800 lock
* Honor LSP with not anymore squeezing something non LSP compatible in
  the same inheritance tree.
* Separate running from result tree.
* Clean up kill logic and early exits on already dead mutations.
* Fix #runnin? smell for reporters.
* Decouple config object from VM state. Makes it serializable to enable
  config loading.
* Fix sequence of global VM events to match PRIOR rspec infects VM with
  gazillions of classes / modules. Thix fixes a startup speed
  degeneration.
* Various fixes to enhance determinism.
* Replace some unneded manual double dispatch with single manual dispatch for
  reporter / runners.
