Fix default settings

[vutran]

This PR aligns the default settings for prettier based on the current settings specified in the prettier repo.

Hi @vutran , thank for submiting a pull request!

vim-prettier default settings differ from prettier intentionally. The default settings used on vim-prettier are meant to follow the same defaults that we use internally at Facebook and on Facebook open source projects.

You can always overwrite the internal defaults by using our configuration hooks on your .vimrc.

Saying that based on your file changes I can see spliting this into 2 potential PR's would make sense:

1. Updating our README.md and doc/prettier.txt to explain the reasoning behind our default settings choice, and being clear that we differ from prettier defaults.
2. Add support for JSON parsing

Updating our README.md and doc/prettier.txt to explain the reasoning behind our default settings choice

We could make it more clear the original intention of the vim-prettier default settings. Please feel free to submit a PR for it or update this PR to it.

Add support for JSON parsing

I have also noticed that you mentioned the support for JSON on the README, that is awesome. But can we do that on a different PR ? To add support for JSON we would also need to do some other updates:

1. copy ftplugin/typescript.vim to ftplugin/json.vim
2. edit the newly created ftplugin/json.vim and change the parser from typescript to json
3. update README.md:
   • update line " flow|babylon|typescript|postcss| to include json similar to what you did on this PR
   • update line \ 'for': ['javascript', 'typescript', 'css', 'less', 'scss'] } to include json
   • update lines autocmd BufWritePre... to include.json
4. same updates done on README.md needs to be done ondoc/prettier.txt
5. update package.json prettier version to the latest prettier that has support for the json parser throught the CLI
6. Test to make sure all is working :)

Thank you very much for contributing!

Also the json parser CLI setting is not yet been released to NPM, however we can have the PR ready for it.

I believe there will be a new prettier release soon that will include it.

Sounds good. I'll update this PR with the changes mentioned and another one with the JSON settings.

Awesome!
