We made too many shortcuts for passing data in and custom schematics could not
work properly.
This is temporary as we will likely move some more logic into schematics tooling
to be able to pass only the raw args and the CLI config, but for now this is
enough to unblock AngularMix.
This PR doesn't change new projects to use 2.4 since I have seen some reports of possible problems in `@angular/*`.
Instead, it:
- removes the dependency restrictions on <2.3
- bumps related dependencies to the minimum that supports 2.4 (`rxjs@^5.4.2`, `ts-node@~3.2.0`)
- builds the CLI itself using 2.4
So if you want to install ts 2.4 in your new project, the CLI itself won't stop you.
Fix#6827
* for several options that are saved in .angular-cli.json, I've added an explanation of what setting in the json file controls that options.
* added an explanation about what --dry-run will output.
* added possible values for --style option
* added respective documentation in the command
* also added less, sass and styl(stylus) as possible style extensions
The motivation for this change is that sometimes people would want to change some of the settings set by the cli durig ng new, that they might have not known or cared about, for example, prefix.
BREAKING CHANGE: Removing the `ng init` & `ng update` commands because their current implementation causes more problems than it solves. Once RC is released, we won't need to use those to update anymore as the step will be as simple as installing the latest version of the CLI.
