(*) Remove the crawl spec abstraction
...
The crawl spec abstraction was used to upload lists of domains into the system for future crawling. This was fairly clunky, and it was difficult to understand what was going to be crawled.
Since a while back, a new domains listing view has been added to the control view that allows direct access to the domains table. This is much preferred and means the operator can directly manage domains without specs.
This commit removes the crawl spec abstraction from the code, and changes the GUI to direct to the domains list instead.

The most common error when dealing with Slop columns is that they can fall out of sync with each other if the programmer accidentally does a conditional read and forgets to skip.
The second most common error is forgetting to close one of the columns in a reader or writer.
To deal with both cases, a new class SlopTable is added that keeps track of the lifecycle of all slop columns and performs a check when closing them that they are in sync.
