Harvest Festival

##0.5.10
* Changed rewards of certain quests seeds to give different crops based on seasons
* Fixed jade not giving sickle for shears
* Allow double flowers to count as flowers
* Removed sneak clicking to gift (use the icon)
* Can now sneak click jade to trade for up to 10 seeds a time (when she trades for them)
* Jade will only remind you about flowers when she still has the quest available
* Items in the offhand now count towards costs, and will be taken over items in the main inventory
* Quests that required you to hold all the items before, will now check for one of the items being held
  but they will take from everywhere in the inventory, prioritising what you are holding first. So for example
  you can now have five of any flowers.
