Added padding - Both inside and outside

Added these functions:

                setPadding(int paddingLeft, int paddingTop, int paddingRight, int paddingBottom)
                getPadding()
                setOutsideVerticalPadding(float outsideVerticalPadding)
                setOutsideHorizontalPadding(float outsideHorizontalPadding)
                getOutsideHorizontalPadding()
                getOutsideVerticalPadding()

and these lines of code:

                params.verticalMargin = outsideVerticalPadding;
                params.horizontalMargin = outsideHorizontalPadding;

                toastView.setPadding(paddingLeft, paddingTop, paddingRight, paddingBottom);

Example code:

                mSuperToast.setGravity(Gravity.RIGHT);
                mSuperToast.setPadding(10, 10, 10, 10);
                mSuperToast.setOutsideVerticalPadding(0.2f);
                mSuperToast.setOutsideHorizontalPadding(0.1f);

This will make the toast appear bottom right on a tablet for example
