//TODO
// Break this up into multiple small webnodes (per page)
// that would make this a lot more customizable
// Only User management, save, load etc should be kept here
// and this node should be expected to be autoloaded.
// It should keep get_singleton() and c++ stuff that deal with users should expect it's presence
// they should use err macros to not crash the app though
// Rename this UserManager
// Also users are useful for not just web stuff, so don't rename them
// Make this inherit from Node instead, only inherit the web user handling from webnodes.
// Also for other webnodes that have admin functionality, break those into separate nodes. It's a lot safer,
// and I think they will work better in this setting like this.

//Add a UserLevelWebPermission WebPermission. It should read a new projectsettings entry, and use it as an enum, that
// can be manipulated form the inspector.

// The RBAC system can probably be removed, as WebPermissions + the editor is a lot more powerful.
