Add an option to display favorites as likes

Is your feature request related to a problem? Please describe. Mastodon uses the "favorite" primitive to indicate that a user liked a post. This verb is often associated with the action of liking a post, something most users associated to "hearting" on more incumbent platforms. This creates a few problems:

• People who approach Mastodon for the first time may not immediately understand what a favorite is.
• Using favorites as a verb, and a star as its matching iconography created a steeper-than-needed learning curve for people who are migrating from other services or clients, as they may be more familiar with the like/heart design construct.
• People who are familiar with bookmarks on other platforms may be confused by the semantic proximity of "favorites" and "bookmarks".

Describe the solution you'd like Add the ability to display favorites as likes. This should be implemented as a toggle (disabled by default), so the user can switch between favorites/stars and likes/hearts.

When the user chooses to display favorites as likes, the following should happen:

• Favorite actions (including notifications) will be displayed as likes
• Stars are replaced by hearts in StatusView and NotificationView
• The string "Favorites" and its noun/verb variations are replaces by "Likes" and its variation
• Favoriting a post should display a cute heartbeat animation, as opposed as a rotating star.

Describe alternatives you've considered No alternative was considered.

I do very much appreciate all the thought put into this, but in the near term I think the app is going to be consistent with Mastodon's web idioms for this
