Simplify logic for pqTruchasRecentProjectsMenu
- Only list resources from builtin server
- Strip "builtin:" from the recent-projects menu
- Hide search box from all attribute views
- Mark resources for removal before closing project (fixes crash)
- Warn user when closing modified project and turn off smtk warning for modified resources
- Replace deprecated
smtk::project::ResourceContainer::getByRole()
