Script binding for the new screen shake effect.
The new lua function mana.chr_shake_screen can cause a screen shake
for a single client with variable x-intensity, y-intensity, decay and
duration.
I also added an example script which causes tremors for nearby characters
with intensity and direction relative to a specific point. The function
is not referenced on the example map because it is quite distracting.
