Sim (#11)

* Wheels animation distance changed to 200*D*LODbias

* Fixed spelling error in event syntax; old one remains for compatibility.

* Spelling error left in log text

* Zamiana metalic na floata z wazonym efektem.

# Conflicts:
#	shaders/light_common.glsl

* Detail normalmap shaders @Jan21

* Explicit type conversion

* Leftover metalic as bool

* Syntax error

* Normalmap sampling inside ParallaxMapping function
