At the moment, certain options and arguments that do the same thing should are not named the same across all schematics. In `ng new` to skip the creation of spec files, one needs to use `--skip-test`, with an alias of `-S`, while in other schematics it is `--spec` and no alias. In the component schematics `ng generate component`, to specify the style preprocessor you need to use `--styleext`, while in `ng new` this is named `--style` We should discuss this, choose the preferred namings and align all the same options to make it easier for the users.
