upgrade Alt-Ergo proofs to 0.95.1
in three cases, we use a proof by an earlier version of Alt-Ergo as a sample for bisection and then reprove it with other provers. Also, moved all sessions in theories/ and modules/ to tests/theory-sessions/. These sessions are not replayed by nightly-builds and should not be distributed. Please, do not run why3ide on the standard library files, make separate files in examples/ using those theories, or just realize them in Coq. Don't clobber the loadpath.
