List Tree Layout Manager

[blueprint]

It would be nice to be able to create custom Entities which derive from CategoryTree.

Also, it would be nice to be able to implement a custom List Tree layout without having to tinker with the source files manually.

For anyone that it interested, this feature actually already exists but is just not made public.

To enable this, copy `applicaton\Espo\Resources\Metadata\app\entityTemp lateList.json` to `custom\Espo\Custom\Resources\Metadata\app\entityT emplateList.json` and edit the file, changing the contents to:

[
   "__APPEND__",
   "CategoryTree"
]

Then Rebuild via the Admin interface.
