Add a Basic Vendor to Tlonsiyya

[Tofflesby]

As it stands, Tlonsiyya has unique access to properties with crafting stations, however the nearest Basic Vendor for crafting materials is all the way in Ramieton, making the already out-of-the-way laboratories much harder to use. Adding a basic item vendor (a la Svetlana, or the traveling merchant in Ramieton) would be a huge help.
