Make many parts of Rails lazy. In order to facilitate this,
add lazy_load_hooks.rb, which allows us to declare code that should be run at some later time. For instance, this allows us to defer requiring ActiveRecord::Base at boot time purely to apply configuration. Instead, we register a hook that should apply configuration once ActiveRecord::Base is loaded. With these changes, brings down total boot time of a new app to 300ms in production and 400ms in dev. TODO: rename base_hook

- # % uses self (i.e. the String) as a format specification and returns the
- # result of applying it to the given arguments. In other words it interpolates
- # the given arguments to the string according to the formats the string
- # defines.
- #
- # There are three ways to use it:
- #
- # * Using a single argument or Array of arguments.
- #
- # This is the default behaviour of the String class. See Kernel#sprintf for
- # more details about the format string.
- #
- # Example:
- #
- # "%d %s" % [1, "message"]
- # # => "1 message"
- #
- # * Using a Hash as an argument and unformatted, named placeholders.
- #
- # When you pass a Hash as an argument and specify placeholders with %{foo}
- # it will interpret the hash values as named arguments.
- #
- # Example:
- #
- # "%{firstname}, %{lastname}" % {:firstname => "Masao", :lastname => "Mutoh"}
- # # => "Masao Mutoh"
- #
- # * Using a Hash as an argument and formatted, named placeholders.
- #
- # When you pass a Hash as an argument and specify placeholders with %<foo>d
- # it will interpret the hash values as named arguments and format the value
- # according to the formatting instruction appended to the closing >.
- #
- # Example:
- #
- # "%<integer>d, %<float>.1f" % { :integer => 10, :float => 43.4 }
