Recreate Gemfile.lock in correct order

I believe the list of gems in the Gemfile.lock was rearranged with a
merge.  A rebundle fixed the order.
Fixes issue with category and guides

Guides were not displaying because of a missing ‘,’ in the meta tag
information in the guides view. Added a helper to generate the meta_tag
options

Also fixed and issue where the categories were not linking to the
correct article urls.

Gave the category factory a more proper title using Faker.
