Allow a defining custom member field on resources

By default, resources routes are created with :resource/:id. A model
defining to_param can make prettier urls by using something more
readable than an integer ID, but since the route picks it up as :id you
wind up with awkward User.find_by_username(params[:id]) calls.

By overriding the key to be used in @request.params you can be more
obvious in your intent.

Remove useless conditional.

There was an example here that mentioned reload_plugins?
but it was deleted. This commit puts another example back.

fix HashWithIndifferentAccess.[] method

ActionController caching small String#split optimization

Reason: This commit changes code that was committed some year
and a half ago. The original code is an ordinary predicate
that delegates straight to a boolean operator with no further
unnecessaru adorments, as clearly explained in #5329.

This change also may confuse users who may now believe they can
rely now on singletons, while predicates in Rails rely on
standard Ruby semantics for boolean values and guarantee no
singletons whatsover.

This reverts commit 6349791d.

Remove ActiveModel::Naming#partial_path

Commit 56089ca9 introduced a backward
incompatible change by changing the method signature of the FormBuilder.
This brings back the same method signature warning in case someone gives
a block to the builder.

Before it was handled by Proc.bind, but since Proc.bind has been
deprecated, this is no longer the case and returned handler
needs to match rescuer.
