Create a Rules UI skeleton & allow to manage components

I did some progress here.

https://github.com/scuts/rules/commits/admin_ui

The following features are implemented now:

• The rules collection (listing) is accessible via admin/config in the "workflow" - section.
• The rules collection has 2 operation-links now: "edit" & "delete"
• The rules collection has a "add a new rules component" link
• Rules components can be Created, Edited and Deleted

This is a very basic implementation. In fact its my first try to work with d8 - entities. As fubhy mentioned in IRC he wanted to create a common ui - branch.

Gonna work on this one this afternoon.

Talked with klausi and dasjo. Baseline with routers and stubs for rules-reactions are there and pushed.

Couple of things todo before pull-request:
- Define access permissions
- Find a way to supplement MENU_DEFAULT_LOCAL_TASK
This should be done tomorrow.

After that we probably want to separate the admin interface to a 'rules_ui' sub-module.

Branch on github: https://github.com/nielsdefeyter/rules/tree/admin-ui-2409239

Rules UI (rules_ui) : 'Administration interface for Rules.' is now a submodule in Rules.

PR: https://github.com/fago/rules/pull/163

has:
- permissions
- overview page so crumbs, tabs are handled well. This page uses systemAdminMenuBlockPage and renders all menu-items one level deeper
- crud for components (was my starting-point, thank scuts)
- stub for settings page

Permissions are implemented in Rules
All other things are implemented in submodule Rules UI

Thanks - that's already a great start! Reviewed it and mostly commented on output strings - please work them in.

Thanks for reviewing. I'll follow up this afternoon.

Fixed fago's comments, except

We actually have multiple tags. I think that's broken right now, but let's do already a proper method names -> getTags() which returns string[].

Don't know howto do this.
Klausi commented on protected $tag (in class RulesComponent line ~70)

  /**
   * The "tags" of a Rules component.
   *
   * The tags are stored as a single string, though it is used as multiple tags
   * for example in the rules overview.
   *
   * @var string
   */
  protected $tag = '';

Prefer to move to follow up ticket.

Sounds good. Let's create an ticket for it then and link in the code. Also the code should add an @todo.

Thanks, merged live during drupal dev days d8rules session.!
