Given the function $f(x)= \frac {1}{3}x^{3}+2x^{2}+ax+b$, $g(x)=e^{x}(cx+d)$, and the derivative of function $f(x)$ is $f'(x)$, if the curve of $f(x)$ and $g(x)$ both pass through point $A(0,2)$, and have the same tangent line $y=4x+2$ at point $A$.  
(I) Find the values of $a$, $b$, $c$, $d$;  
(II) If for $x\geqslant -2$, $mg(x)\geqslant f'(x)-2$ always holds, find the range of the real number $m$.
