Fixed Issue with chrome/edge clicking

Removed from index.html in generated webgl build:

 <div class="footer">
        <div class="webgl-logo"></div>
        <div class="fullscreen" onclick="gameInstance.SetFullscreen(1)"></div>
        <div class="title">2D PlatformerController</div>
      </div>

This causes the clicking to be blocked because the browsers think that it is a text area
