Auto update. Increased total vendor item count from 40-50.

Added a dialog interupt to the final dialog chain for the Tech visit.
The final chain had an interjector node and im guessing that cancelled the interupt on the begining of the dialog so i added the interupt after each interjector.
The first two chains worked fine and have no interjector lines.

Update~ repaired dialog to work with new caravan visit system.
increased total amount of goods they offer each visit to make sure all items spawn.

Added tech hunters notes to vendor to thin out Ai and engineers research abit.
Changed to 5 days and chance to 0.2
