testing out circleci build triggers with a PR that tidies up the README badges

- remove somewhat redundant `project: ipfs` badge so they fit on 1 line. The link to the website is the url field for the repo.
- Use shields.io "flat square" style for godoc badge to match the others
- Use shields.io for the circleci badge too.
- re-order to be more visually pleasing.

fix: ignore nonexistant when force rm

- Make `ipfs files rm --force /nonexistant` succeed when the path does not exist.
- Add shaness test for removing nonexistant paths
- Refactor duplicated code to find a parent dir into a function

I've been writing scripts against the files api, and having to stat things before removing them is a pain. So this PR aims to make --force do what I'd expect it to.
