Version 0.6.1 is out

After a good bit of work, version 0.6.1 of "2D Game Development: From Zero to Hero" is out.

In this maintenance release we have:

• A fix for a wrong implementation of invincibility frames
• A better explanation and diagram for "quad trees"
• A new section about "bullet hell games", for now just filled with placeholders
• Better definition of the "game development" roles in the "Project Management" section
• Added a section dedicated to "randomizers" in the "Engaging your community" section, to be further expanded in the future
• Added some terminology and basics for DAW Software and Music Trackers
