clean up main script / arg parsing

This commit is a (more or less) complete rewrite of roverlay's arg parsing.

Notable differences/changes:
* fixes name clash issues / "hidden" imports; all modules can now be imported
  at the beginning of the file
* usage of a "runtime environment" data object instead of global variables
  run_<command>() functions use this environment (passed as first arg) now
* extensible/modular arg parser creation, which allows to write helper scripts
  with a reduced set of options
