Male portrait update

The update for my pixel art portrait generator introducing male characters is now available.

I had problems making the faces look male. They looked androgynous at most. Finally, I realized what was missing - beards!
So, here you go.

Changelog:

• Male portraits, including new cloths, hair styles, beards and eye shapes.
• More hair styles.
• Glasses and headset.
• Synchronize colour pickers.
• Store portrait data when pressing the save button.
• Use GLES2 instead of GLES3 renderer.
• Use new Godot Engine version.
