[spell] Roll SCOWL dictionaries for en-US & en-CA.
Updated the en-US and en-CA dictionaries to the latest upstream version
from SCOWL, but made sure that "alot -> a lot" correction does not
disappear, as it is not in SCOWL yet.
The updated dictionaries support typographical apostrophes.
Because both aff and dic files changed, we incremented major version to
6-0. That's 1 higher than the highest major version of any dictionary.
