Bundle autocomplete-plus

[confused-Techie]

This PR follows all previous guidelines on the topic.

• Adds and updates a package-lock.json
• Removes the MIT license file as it matches the repo license
• Rebrands the README.md and package.json

Otherwise this PR bundles autocomplete-plus updating the pulsar package.json and yarn.lock

FYI: Seems an error was made when bundling and the incorrect commit SHA was used, missing some of the changes available on the tagged ref we were previously using. So this bundled autocomplete-plus is still using the outdated Atom Jasmine3 test runner. This will be resolved, but until then should not be merged since while tests pass locally, they do not pass in Ci

Alright, sorry about the temporary error.

This PR is now good to review with:

• find-and-replace: 66 Failures (We expect 51 ± ~10 so this seems to fall into the expected range)
• symbols-view: 2 Failures (We expect 2)
• tree-view: 2 Failures (We expect 2)

So the tests are right where we would expect them, other than find-and-replace being a slight range that is hard to predict. So essentially this PR should be good to go.

I can confirm this 100% matches the previously specified 1f056ef commit of our fork of autocomplete-plus (see this branch https://github.com/pulsar-edit/autocomplete-plus/tree/fix-outdated-test-lib)...

Other than in README.md deleting an obsolete Travis CI badge and rebranding an instance of "Atom" to "Pulsar", which makes sense to me.

Approved!
