Subject: [PATCH] 48 builder frontend 2 (#70)

* Implement collapsing component hierarchy.

* Save screen when adding new components.

* Allow creation of nested child components.

* Fix level-based indentation of hierarchy.

* Rename updateComponentProps to setComponentProps

* Save layout information to the disk.

* Cleanup: switch to autosubscriptions to prevent memory leaks, remove unused imports.

* Remove unused css.

* Fix incorrect subscription.
