Add items to the search table for tiles with constructed Fonts

[NearNihil]

Since building a Font requires the construction of several superheavy items, I think it'd be thematically neat if they had a bit of mechanical flavor too.

I propose to add fresh fruit and forest alchemy components to a tile's search options if the font was made by a LS with Fruit Trees, gems of any type from an Elementalist's Geysers, and Soul and Blood Ice to Rusted Iron Spires from a WM. They should be found 10-15% of the time so as to not overpower the original tile flavor. Adding the same amount to search chance would be neat, but I haven't considered how bad or broken this would be and would have to run the numbers first. However, since this only concerns outdoor-only locations, it could be ok.
