closes #5, fixes archives ordering in sidebar

[Brikky]

Closes #5
Sorts the @Archives array before it's sent back by using a multi-value comparison, ensuring archives are correctly sorted by year and month starting from January (or the earliest month with posts.)

Will this play nice with #24 ?

[Brikky]

Yes, it's just reorganizing the array of Archives in the same method that builds it.
I tried it out and it works.

Is the original SQL query not enough? See

publify_debugging_lab/publify_core/app/models/archives_sidebar.rb

Line 30 in 9fb5f02

article_counts = Content.find_by_sql(["select count(*) as count, #{date_func} from contents where type='Article' and published = ? and published_at < ? group by year,month order by year desc,month desc limit ? ", true, Time.now, count.to_i])

[Brikky]

Yes, though the ordering is reversed.

Looks like that bug didn't actually make its way into the code.
