Settings UI: Breadcrumbs in settings

[iLLiCiTiT]

Description

Orientation in settings UI can be a mess when we're communicating with anyone who's interested in them. Adding breadcrumbs adds easier access to specific items and can open doors for docstring directly in settings UI as it defines "context" of settings.

Changes

• added breadcrumbs widget to settings UI
• setting entities has collect_static_entities_by_path which collect all path and entities that are not dynamic
• list entities has getters and setter implemented
• reduced number of widgets with replacing Spacing widgets with stretch

Notes

• it's first version
• hints of paths works only for static entities (not dynamically created e.g. in list or modifiable dictionary)
• path is created from key not from labels

When I want to insert a known path, the settings jump to the right place and expand the settings correctly for the very first time. The second attempt only expands the required settings but does not move and shows the right items.

Tested for:
project_anatomy/templates/work/folder
project_settings/global/publish/ValidateVersion/enabled

It was issue with checkbox item. Should be fixed now.
