Travis and Appveyor configs

[MatthieuDartiailh]

@matthew-brett appveyor is not used anymore by this project and Travis is migrating from Travis.org to Travis.com (and we need Travis for exotic architecture). Could you disable Appveyor and switch Travis or let me know how to do it ?

OK for me to delete the Appveyor project (and all artifacts)?

For travis-ci.com - I must admit I was sitting and waiting to see what happened when the changeover actually happened. I haven't migrated anything recently because I have run out of credit on travis-ci.com. In truth, it is probably better for each organization to migrate their own repositories; having a single MacPython organization is just going to mean that we exhaust each others' credits on a single account.

Thanks @matthew-brett. I will try to migrate the repo to https://github.com/nucleic which is the organization under which kiwi lives. I wish travis would support multiple workflows like GHA...

You can delete everything related to appveyor including the artifacts yes.
