Improved AI Upload intercom coverage.

Improves the coverage in the AI core by adding a second intercom, as people were often unheard in the upper left corner.

This does make it more difficult to prevent the AI from eavesdropping, but if the situation is such that you don't want the AI to listen then you probably want to cut the intercom wires anyway.
