Pimcore: [UI] Add setting for number of items in tree before pagination

Feature Request

Feature description

I'd like to request something similar to the forum topic here: https://www.pimcore.org/board/viewtopic.php?f=22&t=740

It'd be great to have an option (inside a config file would be enough) to set the number of items in the navigation tree. It's quite annoying to have pages instead of scrolling the tree in many cases. We'll scroll anyway in most cases.
It could be a nice addition to the possibilities given with Custom Views so there could be specific settings for documents, assets or certain object folders.

Config for this would be nice
