Add points icon to table & sparkles

[garethfuller]

If a pool has points as rewards add the points icon to the pools list table beside the APR stars. If possible, detect if any pool in the list has points rewards and if not remove the margin created to hold the points icon, see screenshot.

This has been implemented.

Update: "The points logo is also in the Pool header section, but I think we should also repeat it next to the sparkles in whenever an APR is displayed"
