Added precision and mode arguments to Vector3::round() (#1256)

Browse Source 
If the precision is positive (i.e. there are numbers after the decimal point), the results should be floating-point numbers rather than integers, hence the additional check.

Even if the precision is negative or zero, the $mode parameter may still be useful.
