v0.8.13

• Additional French language translations [Tao Galasse]
• Add support for admin-level hook definitions
• Improve default handling of JSON attribute form fields
• Improve handling of error responses
• Remove default JS response handlers for admin resources. They can be added manually as required using:

controller do
  def show
    super do |format|
      format.js
    end
  end
end

• Remove clear button from disabled date/time pickers
• Disable select fields and date pickers when admin is read-only
• Allow routes block to be called multiple times
• Fix error when using selectable_column
• Fix deprecation warnings in Rails 6

This will likely be the last release before #195 is merged in (which will then be released as 0.9.0).
