Reviewers

Datagrids now have a separation of state and definition. This requires
some changes in Column subclasses to make use of the new state
parameters.

As part of the new fixes, we're also able to fix sorting of the review
request ID column, which broke in RC 1.

Unit tests pass.

Added every column. Rearranged columns. Sorted several of them. Removed columns.
Everything worked.

Tested the review request ID column with both global review requests and Local Sites.
