Preparation to commit the bug fixes and extensions to $specint

The last days I collected the changes and extensions in the file hypgeo.lisp to
prepare the upload of the file. I changed and added as few code as possible. I
have included only code which is necessary to get all tests I have collected
from A&S and EqWorld to work (correct result or at least a correct noun form).

I have one problem with the algorithm for integrals like t^v*(a+t)^w. It works
for a lot of cases very fine. But for one case I get wrong factors. Im searching
for the reason. If I can't solve the problem, I will implement the return of a
noun form (better a correct noun form and not a wrong result).

I would like to upload additionally the tests I have collected from A&S and
EqWorld (about 230). I think it is the best to put these tests in a separat test
file. A good name of the new test file would be: rtest_hypgeo.mac. I'm preparing
this test file. Is it okay? Should I also extend the list in the file
testsuite.lisp accordingly?

Furthermore, 3 tests in rtest14.mac of the testsuite has to be updated (Problem
55, 150 and 157). In all cases the noun form is improved. There is no other
change necessary. Should I do the changes and upload the file?

I think I need some days to finish the work.
