Create an advanced mode for the Effect composer

Advanced mode for the Effect Composer is needed to simplify the use of Effect Composer for users who don't do shader coding.

Advanced mode can be switched on/off. There would be a toggle button in the header of the Effect Composer.

You can see the placement in this picture (the icon in the button is still subject to change as of writing this):

If advanced mode is NOT ON

• The user does not see Add property or Show code button in preset effects
• The code button, which shows the whole effect code, is hidden

If advanced mode is ON

• The user sees Add Property and Show code buttons in preset effects
• The code button in the header is shown
