Batch repo enhancements

Let me please propose batch of changes to the DX, so it’d be easier for others to contribute. Please let me know what you would approve, so I’d know what to help you with 😃

Todo (Not started yet)

• add automated releases generation and make commits messages more strict
  • as a user of this library, it was a bit time consuming to browse commits to realize what changed between beta versions

Completed

• use typescript-eslint instead of tslint
  • it’s been almost 2 years since the standard in TS linting is ESLint, more info
• add .log files to .gitignore
  • for example, there’s already a mistakenly uploaded yarn-error.log
• bump prettier & use community defaults
  • let’s use the defaults, so it’s more likely to please higher % of contributors
• add .npmignore to exclude unrelated files from the deployed package
  • improve the files + exclude instead
• remove empty dependencies object from package.json
• add husky to add git hooks
  • it’s important to automatically prevent issues like in #218 from happening, when there are bunch of unrelated formatting changes
    • at least automatic code formatting should be in place
• add official funding references of your GitHub sponsors link to the package.json
  • I suggest to start with the use described in this PR from react-virtual

@o-alexandrov, are you still working on this? I’d like to contribute on this if possible. @colinhacks, I could start getting separate PRs up for each of the points listed in the initial message. Let me know your thoughts when you get a chance, and I’ll get the first PR pushed right away 😊

@o-alexandrov I removed tslint entirely since I never actually used yarn lint and it wasn’t integrated into the build process in any way. So perhaps the first item should be “Add eslint-typescript”.

I checked off “funding”.

I also checked off “prettier” having just merged @jameschensmith’s #260

I also checked off “exclude”. It’s now using includes (not files) and excludes to prevent unused files from getting deployed. I just merged that change last night.
