Update 3.0.0

• New interaction type: Radial.
• Shizuka added to the roster as the first Radial type interaction.
• Yaku and Meme are now legacy interactive arts. They may be reworked into future interaction types

This Shizuka update is a test of how to contain interactive art within a single HTML file, so it can be viewed and shared around without any web server or installation. I see this as having potential of encouraging more types of arts (or commissions) among artist community, even if it takes years to develop.
