Feed Failure Modal Updates

The feed failure modal is currently a bit inconsistent with our other modals:

• "re-load" is one word and should be "reload"
• action button should use our primary color as a background color (blue)
• action buttons should be right aligned
• buttons should have text-transform: uppercase;

It is possible that the option that we are offering is the same feed that the user is attempting to load in the first place. I wonder if a snackbar is more appropriate here:

• snackbar, feed failed to load
• we are not blocking in this case, the feed will attempt to reload on the next try
• this avoids the case where you leave the application open and inevitably come back to the feed failure dialog even though you haven't interacted with the interface in 24 hrs. If we used a snackbar the feed would reload when the feed/internet connection is made available.
• discuss we could also say, "browse in offline mode" which would disable auto update.
