files to remove / clean / update

going through the repo I think there is a bit of cleaning that can be done: - [ ] .travis.yml : does not seem to be used anymore - [ ] Makefile and Makefile.win: several recipes can be removed - [ ] Changelog needs updating AFAICT - [ ] TODO should probably be removed (maybe open an issue to store its content instead) - [ ] several scripts in the tools folder feel like they are way too old to be useful: e.g tools/bisect_nose.py - [ ] lgtm.yml - [ ] doc/misc/pylintrc
