Redo Sprig gallery/gameplay experience

[recursiveforte]

I propose we separate the editor from the experience of playing a game. When opening a game, we should only show the game and its description/author/metadata - there should be a button to open the editor interface, which includes the code and help panes. This helps turn Sprig into more of a "game platform" instead of a platform purely focused on creating games, drawing people in who would not otherwise play games in the gallery.

The former interface - focused on gameplay - should show the game as the largest element and have the following functions:

• a share button
• a button to open the code editor
• a button to upload the game to the console
• a description (determined by the text in the first comment block, after the metadata).
• information on the submitted date, author, # of views, and an upvote function
