Enhancement build, structure and fix jest tests

[rivajunior]

Is this a fix, enhancement or language pack?

This is both, fix and enhancement.

On this pull request I've made the following changes:

• Changed _custom.scss for _variables.scss, how Laravel uses

• Added Fontawesome web on scss to remove Fontawesome SVG used on JS, because it doesn't work on old browsers since Mix isn't processing node_modules dependencies. (Plus: build size gets lighter)

• Simplified .babelrc putting browserlist configuration on package.json. In addition to that, I've fixed deprecation warning because of use of uglify option who have changed to forceAllTransforms.

• Enforced Unix newlines for some files, like bootstrap does

• Fixed Jest tests.

  • Added Jest dependencie who was missing.

  • Changed deprecated shallow to shallowMount

• Made scripts on package.json work with Yarn and NPM, using $npm_execpath how as suggested on 5.8 Suggestion : improve package.json compatibility with yarn #1216.

  • The problem is a Yarn warning which says basicaly that it won't work in the future:

    • warning From Yarn 1.0 onwards, scripts don't require "--" for options to be forwarded. In a future version, any explicit "--" will be forwarded as-is to the scripts.

• Removed unnecessary node_modules/.bin/whatever path from scripts on package.json. See npm-run-scripts

Great PR. Thanks for listing all the changes with sources, I have no problem with any of this I just need to test it all my self before merging in.

I forgot to say that I've tested the scripts on my windows 10 (bash, cmd, powershell) and on ubuntu 18.04 (homestead)

The only difference I see is that font awesome can no longer be used on the backend, I get that coreui uses simple line icons (which is annoying to begin with) but we should still have the option to use them globally. So i'm probably going to modify that.

Edit: There are actually a few on the backend that don't currently appear because of this, so we have to make it global somewhere.

Don't worry, I'll do that.

I don't have sure, but I think we don't need to use Simple Line Icons. It is used on CoreUI examples, but we not obligated to use it. So if we remove and use only font-awesome, it can be lighter than use two icon fonts.
