GOLDENG 92: Allow all users to view/edit snoovatars

[helen-tang]

This PR addresses: https://reddit.atlassian.net/browse/GOLDENG-92

• r2: Profile Page option to “View / Edit My Snoovatar” for your own self will be available to all users, not just Premium users

Originally, users who were not gold users were not able to view their snoovatars. We now want to open that up to all users.

UPDATE This PR also removes this dialogue from the Snoovatar creation page as it's no longer relevant:

The r2 link is still hidden behind user.gold (in reddit-public)

@jonowar @MelissaCole Yep! I have a separate PR incoming for R2! Just got caught up in some Snoosweek things so I haven't pushed it up.
