v0.20.0

• Fix #111: Generic<\namespaced\class-type> not prefixed. Thanks @ravinderk e05eb33
• Add strauss replace command (e.g. if you fork a project and want to change its namespace). Fix #125 ReplaceCommand.php
• Lots of refactoring

The next release will prefix global functions. Since that's a breaking change for long-term users, I will wait to test it more: e661e94...ac404b3
