Subject: [PATCH] Aesel: the account's braincells at the bottom right
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

After this thread's tokens and price, the status line shows the account's
braincells — today's free allowance left plus bought — read from
/api/easel-credits at start, on sign-in and after every turn. Every
session shows the same number, so it says where the whole account stands.
