Change the code to comply with eslint and vice versa

[Maks-s]

The title says it all 😃

Small tweaks / fix included which didn't need their own PR :

• remove sync button if sync isn't enabled
• ignore .vscode folder

About vscode It's may be a good idea to include it with a setting configuration and module we may use so that we all have the same dev environment :thinking:

... Just an idea ...

I had the idea after hitting Ctrl+S for saving under vscode ... Part of the code was formatted automatically ... :disappointed:

Good idea @funilrys

Also, should we force LF on windows to prevent massive errors from eslint (because of CRLF) or should we remove the linebreak-style rule from eslint ?

EDIT : See https://eslint.org/docs/rules/linebreak-style

[funilrys]

The problem with LF is actually more complicated because everybody should actually commit/push with LF instead of CRLF.

I think that we should do https://eslint.org/docs/rules/linebreak-style#using-this-rule-with-version-control-systems

.gitattributes:

*.js text eol=lf

Before adding Travis CI we should do #8 😉

I think a lot of this was on me. I went through and cleaned up a bunch of the eslint errors and then made a bunch more with the intent of getting back to them eventually. I'll get into better habit about that.

The PR looks good. Merging.
