chore(distro): rename dist files and omit .map

This renames distribution files to:

  {variant}.development.js
  {variant}.production.min.js

Additional changes:

* drops .map file; users should use .development bundle
  for easier debugging

Related to #725

BREAKING CHANGE:

* distribution files have been renamed; users must update their
  apps accordingly if they'd like to use newer bpmn-js dists
