Add the possibility to request server analysis at the end of the game.

[veloce]

Just like in the website, a "request server analysis" button should be added.

It should appear at the end of the game in the popup showing the result, on top of the other buttons (rematch, etc).

It should also be possible to request it from the game analysis page. Right now we only show the analysis summary button if the analysis is already available:

Instead this button should always be there if the analysis is loaded from a user game (GameFullId available). And instead of the graph and analysis summary, a "request analysis" button should be displayed if the analysis is not available yet.

Requesting a new analysis for a game is done with this endpoint:

POST /<gameFullId>/request-analysis

One should connect to the game socket to follow the game analysis progress and notify user when it is done (enabling highlight in the bottom bar button should be enough).
