Adjusted activation timer for 'smile' easter egg

Updated smile easter egg:

The 'smiling' cat is now not click event based anymore. You have to 'pet' the cat using your curser for it to 'smile'

Heavily improved performance when certain user properties are toggled off.

When all possible customization turned off the stats are:

-20 rendertarget changes
-21 draw calls
-51MB texture memory
-under 5K primitives
-3 framebuffer copies

Hiding a layer does not deactivate the effect applied to that layer. User properties now toggle the affected layer AND the effect tied to that layer. Cloud animation, background blur, audio glow, reflections and all media info and clock shadows are now toggled off completely when not in use.

Character glasses now use SSR too when reflections are enabled.

Maximum cloud opacity has been adjusted and made customizable from within the cloud settings.

Procedural clouds now have 3 presets that are all customizable. Based on Worley, Perlin and Simplex noise generators respectively. Yet again made possible by Gariams Procedural Noise Effect!

Last update accidentally included internal project layers used for easier editing. I usually delete these before compiling to improve performance but I somehow forgot to do that last time.

Day and month name are now available in french, spanish and german in addition to the standard english ones.

Changed standard properties.

Improved 16:10 compatibility for mostly my own personal benefit.

Added pseudo-random "ear flick" animation to the cat.

Adjusted background blur.

Minor character animation changes.

Easter Egg:
Added click-event interaction to the cat. This only works ONCE after applying the wallpaper.
Open the wallpaper and click anywhere on the cat character to make it "smile" at you.

Media info now works with any mediaplayer/website.

Minor optimizations.

Removed the stars as they weren´t visible for quite a while now anyway.

Birds have SOMEHOW been broken by the 2.3 update and so I replaced them with the ones I used in "Fallen Tower".

Floating point errors I guess?
