rework mesecons debug to be more flexible (#7)

* add proper settings (untested)

* more constants -> settings

* normalize whitespace between code files

* refactor globalsteps in order to simplify logic

* minor refactoring

* rename file

* use mod_storage for persistent data; optimize context initialization

* refactoring (moving files around)

* rewrite penalty

* add settings; document; allow changing while game is running

* add command to update settings

* update init after splitting commands into files

* fix bugs; add debugging tools; too much for one commit...

* fix whitelist conversion

* add adjustable blinky plant to timer overrides

* add some more mesecons nodes with repeating timers

* resolve luacheck warnings

* tweak hud

* Update documentation; parameterize more things; refactor some logic for readability
