Handle buttons to AREnv 1 and 2

[petrepa]

Features 🎆

• The numeric 1 button 1️⃣ should take the user to AREnv and the scene should have occlusion manager enabled
• The numeric 2 button 2️⃣ should take the user to AREnv, but this time the scene should not have occlusion manager enabled.

Ideas

• Make boolean that gets is either on or off for either button 1️⃣ or 2️⃣. This boolean should be read by AREnv scene and toggle AROcclusionManager appropriately
