Added a couple of variables for further default theme customization.

• Adds RailsEmailPreview.find_preview_classes(dir) that also finds classes in subdirectories.

• Changes the default initializer to load classes like this:

  RailsEmailPreview.preview_classes =
      RailsEmailPreview.find_preview_classes('app/mailer_previews')
  

Breaking: REP now uses a lightweight default theme with no dependencies by default.

If you are using REP with the Bootstrap 3 theme, here are the configuration changes you need to make:

• @import "rails_email_preview/bootstrap3" instead of rails_email_preview/application.

• Add the following styles configuration to your REP initializer:

  config.style.merge!(
      btn_active_class_modifier: 'active',
      btn_danger_class:          'btn btn-danger',
      btn_default_class:         'btn btn-default',
      btn_group_class:           'btn-group btn-group-sm',
      btn_primary_class:         'btn btn-primary',
      form_control_class:        'form-control',
      list_group_class:          'list-group',
      list_group_item_class:     'list-group-item',
      row_class:                 'row',
  )
  

The following REP internal class names have changed:

• .rep-email-options is now .rep--email-options.
• .rep-headers-list is now .rep--headers-list.
• .rep-email-show is now .rep--email-show.
• .breadcrumb is now .rep--breadcrumbs.
• .breadcrumb .active is now .rep--breadcrumbs__active.
• .rep-send-to-wrapper is gone, but now there is .rep--send-to-form.

All REP views are now wrapped in a div with the rep--main-container class.

REP no longer depends on slim and slim-rails.

Fixed minor email locale handling bugs in navigation and the CMS integration.
