[spell] Roll SCOWL dictionaries for en-US & en-CA.

[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.

Rachel, PTAL.

RS LGTM (change looks correct, but I didn't verify dictionary contents
individually)

https://codereview.chromium.org/966563002/diff/60001/en_CA.dic
File en_CA.dic (left):

https://codereview.chromium.org/966563002/diff/60001/en_CA.dic#oldcode50
en_CA.dic:50: AIDSes
Really? We had AIDSes in the dictionary? That's... interesting :)

Ben, OWNERS PTAL.

Note that I've added an OWNERS file with some of the current spellcheck
maintainers.

Carlos, OWNERS PTAL.

Note that I've added an OWNERS file for third_party/hunspell_dictionaries with
some of the current spellcheck maintainers.

[please use gerrit instead, 2015-03-06 23:39:12]

Noticed that third_party/OWNERS says to TBR cpu@ or darin@ for changes within
third_party. Therefore, I am TBR-ing this patch and removing
third_party/hunspell_dictionaries/OWNERS.
