Production build without "transpileOnly: true"

[DorianGrey]

With the currently used transpileOnly flag enabled for ts-loader, some issues with the generated code might occur, esp. regarding const enums, like described here:

microsoft/TypeScript#16671
TypeStrong/ts-loader#331

To avoid doing duplicated work, type checking via fork-ts-checker-webpack-plugin should be disabled. However, it cannot be disabled without disabling it at all. If that is the only alternative, externalizing the linting step from the build to a separate task - executable on demand, forcefully executed on pre-commit should be useful. Already did that in some other projects with great success.
