Dmitry S 8c788005c3 (core) Implement much of the general AccessRules UI.
Summary:
- Factored out ACLRuleCollection into its own file, and use for building UI.
- Moved AccessRules out of UserManager to a page linked from left panel.
- Changed default RulePart to be the last part of a rule for simpler code.
- Implemented much of the UI for adding/deleting rules.
  - For now, editing the ACLFormula and Permissions is done using text inputs.
- Implemented saving rules by syncing a bundle of them.
- Fixed DocData to clean up action bundle in case of an early error.

Test Plan: WIP planning to add some new browser tests for the UI

/**
* This module provides a urlState() function returning a singleton UrlState, which represents
* Grist application state as encoded into a URL, and navigation functions.
*
* For example, the current org is available as a value or as an observable:
*
* urlState().state.get().org
* computed((use) => use(urlState().state).org);
*
* Creating a link which has an href but changes state without reloading page is possible with:
*
* dom('a', urlState().setLinkUrl({ws: 10}), "...")
*
* Grist URLs have the form:
* <org-base>/
* <org-base>/ws/<ws>/
* <org-base>/doc/<doc>[/p/<docPage>]
*
* where <org-base> depends on whether subdomains are in use, i.e. one of:
* <org>.getgrist.com
* localhost:8080/o/<org>
*
* Note that the form of URLs depends on the settings in window.gristConfig object.
