- Update supporting\validator\bin\Newtonsoft.Json to 11.0.2
- **HIGHLIGHT**: support for regex operator in JSON Paths
- Latest Newtonsoft.Json version is 12.0.1, which has some compatibility issues with Json.Schema 3.0.10 and PowerShell Core 6.1.12 (On my PC)
- Update supporting\validator\bin\Newtonsoft.Json.Schema to 3.0.10
- Use .NET 4.5 instead of .NET 4.0, since Scoop's requirements is [.NET Framework 4.5+](https://github.com/lukesampson/scoop#requirements)
- Modify `json_path()` to escape `$version` substitutions when `$jsonpath` has regex
**EXAMPLE OF JPATH REGEX**
```json
"checkver": {
"url": "https://dist.nuget.org/index.json",
"jp": "$..versions[?(@.displayName =~ /.*recommended.*/)].version"
}
```
* makes changes to almost all main repo files to be in accordance with .editorconfig
* some files in "test\fixtures\..." were left alone to avoid breaking tests
* NOTE: whitespace changes *only* (`git diff -b` shows no changes)
