Replace Crystals/Crate fragment shop with a Scroll shop

[Terran]

Give Forerunner Fragments a use! Each day, 5 of a specific scroll will show up in the shop. Players can only buy one scroll out of the shop, per player. These scrolls should be untradeable, so its not just another "get X item sell for Y coins". Only that scroll for the day. Something like

50% chance of an easy (10 Fragments)
25% chance of a medium (25 Fragments)
25% chance of a hard (50 Fragments)

All numbers or stats can be changed or whatever, just a ballpark.
