[IMPORTANT] Make "sprockets/railtie" require explicit.

This makes "sprockets/railtie" explicit. This means that sprockets will
be loaded when you require "rails/all". If you are not using requiring
"rails/all", you need to manually load it with all other framework
railties.

In order to be complete, this commit also adds --skip-sprockets to
the rails generator.
