Given the polar equation of curve C is $\rho=2$, and a Cartesian coordinate system is established with the pole as the origin and the positive half-axis of the polar axis as the x-axis. The parametric equation of line $l$ is $$\begin{cases} x=1+t \\ y=2+ \sqrt {3}t\end{cases}$$ (t is the parameter).
(Ⅰ) Write the general equation of line $l$ and the Cartesian coordinate equation of curve C;
(Ⅱ) Suppose curve C undergoes a scaling transformation $$\begin{cases} x'=x \\ y'=\frac {1}{2}y\end{cases}$$ to obtain curve C', and let M(x, y) be any point on curve C'. Find the minimum value of $$x^{2}- \sqrt {3}xy+2y^{2}$$ and the coordinates of the corresponding point M.
