Part of incremental effort to get agora UX on par with binance UX
Both Binance and Coinex show the amount of token for sale at each limit order price. They also show the cumulative amount as you proceed further up the depth chart.
I think it is too much info to show these quantities all the time in Cashtab, esp as token quantities can be quite large. But would be nice to show with a tooltip.
Here we introduce just the amount of token listed by a specific agora offer in a tooltip. We will add the cumulative amount in a later diff.
