More love for tables

**Changes**

* Removed confusing `::` separator between type and method names. It used to signal the difference between static and instance methods, but this is unnecessary thing.
* Fixed table structure – space is not wasted for short columns (Id, State, etc.)
* More space for job method name in tables to support longer ones.
* Display ScheduledAt time on scheduled jobs page.
* Added batch operations for all pages, including succeeded jobs page – you can now do what you want with your jobs.
* Job methods are links now, you are not required to aim their ids anymore.
