This change allows projects and swimlanes to be configured with task limits that apply to their whole scope (i.e. all active tasks in a project or swimlane, respectively), as opposed to the usual per-column task limits.
* Fixed missing metadata option from project "create from"
* Added option to clone project custom filters
* Added append option to custom field tests
* Added a test that uses the "append" option
* Fixed disabled swimlane duplication error with Postgresql
