Make SPFx projects compatible with TSLint VSCode extension
Make SPFx projects compatible with TSLint VSCode extension by either moving the tslint.json file to the root folder or by creating a new tslint.json at the root that instructs the VSCode extension to look for rules on the config folder
The tslint.json in the config folder is a custom format and not compatible to tslint for VSCode. Only the lintConfig attribute is the "normal" tslint.json. This is very confusing. The rules should be in a classic tslint.json in the root (or src) and the config values should be in the config folder, but with a different name.
