Use DLMF 8.8.9 to expand gamma_incomplete(a+n,z)

Can't figure out what the current algorithm is for computing
gamma_incomplete(a+n,z) for numerical n, but the result is basically
z^(a+n-1)*exp(-z)*P(1/z), for some polynomial P. The coefficients of
the polynomial has lots of gratuitious negative signs.

Let's replace this with a know reference using DLMF 8.8.9. This gives
the equivalent form z^a*exp(-z)*P1(z) where P1 has simpler
coefficients (fewer extra negative signs).

Fix maxima-local.in, that it works, when called from another directory.

Thanks Gunter and Robert for fixing my code.

Windows installer: Use more recent VTK version (for 64 bit installers).

The newest VTK installer is 7.1.1 for 64 bit (they did not release
it for 32 bit).
There was a discussion on the mailing list that keeping the same
version for 64 and 32 bit is not required and I should use the
most recent version and the versions can differ.

This fixes ticket https://sourceforge.net/p/maxima/support-requests/70/

Windows installer: Use more recent SBCL version (for 64 bit installers).

The newest SBCL installer is 2.0.0 for 64 bit (they did not release
it for 32 bit).
There was a discussion on the mailing list that keeping the same
version for 64 and 32 bit is not required and I should use the
most recent version and the versions can differ.

Windows installer: Use current Gnuplot version (for 64 bit installers).

The most recent gnuplot installer is 5.2.8 for 64 bit (they did
not release it for 32 bit).
There was a discussion on the mailing list that keeping the same
version for 64 and 32 bit is not required and I should use the
most recent version and the versions can differ.

This fixes support request #71.

Add comments for gamma_incomplete(a+n,z)

For n < 0, it looks like the formula from functions.wolfram.com. I
don't know where the formula for n > 0 comes from. It'k kind of like
DLMF 8.8.10, but I can't get the pochhammer term in the sum.
