Clamp NavigationMesh sample_distance above zero

Browse Source 
While default ReCast library has support for 0.0 'sample_distance' the Godot implementation does not an crashes.
Previously Godot would set all sample_distance values below 0.9 to 0 which causes the crashes.

This limits the sample_distance range selection to 0.1 - 16.0 and also clamps sample_distance that are below 0.1 before ReCast receives them.
