Fixed for the next release; waiting for the long test before it ships.

The mod comparison listed DLCUltraHighResolution.esm as missing on a game that has the file. It is a texture pack with no game records, so one player having it and another not makes no difference in a session. The next release leaves it out of the comparison. We tested it on two real games with the pack on only one.

Built · Written, with tests, waiting for review.
Reviewed · Passed code review.
