v1.3.0 Drastically improved make:entity Command

Woh! This release contains just one new feature, but it's a big one:

• Drastically improved make:entity command, which now supports
  adding fields, relationships, updating existing entities, and
  generating (with the --regenerate flag) missing
  properties/getters/setters (effectively replaces doctrine:generate:entities)
  • thanks to @weaverryan in #104
