Add support for galleries. Alphabatize post formats.
Include 'Galleries' as an archive page title
Update custom image size names

Since we're using them for more than just Image format posts now we'll
use a bit more general size name.
Update Image format posts to use the new custom image size
Exclude Gallery posts from the homepage
Switch to using full-sized images on attachment pages
Remove bottom navigation on single permalinks

Style updates

Includes the layout for attachment pages and gallery format posts.
Minor spacing and typography updates as well.
Remove Status format posts from the homepage
Set avatars in comments to 50px wide
Use default _s markup for navigation menu

Not sure what happened earlier. This fixes an issue where mobile styles
weren't playing nicely due to mismatched markup.
Style updates focused on responsive changes

Included:
- Mobile navigation menu
- Spacing cleanup across viewports; trying to keep things consistent
Link post thumbnail to permalink for Gallery and Image format posts

This gives a bigger target for the permalink and is a bit more standard
behavior. Felt weird to not have it link.
Typographical cleanup

Includes styles for headings, tables, definition lists, and more.
Removes the transition on links.
Adjust alignment and display of genericons in post-meta
Set custom excerpt length to 50 words.
Remove hacky post-format exclusions in favor of homepage template

This removes the hacky post-format exclusion that used to run in
functions.php. The problem with that was that it was hiding
non-standard post formats from XML-RPC calls as well.

This sets a custom homepage template and content query to pull just
standard posts. It was adapted from Twenty Eleven.
