techTable

We need this to be a separate table, and NOT the topTable, because inhales When call setConnectingLines we need to pack() the table so that the lines will align correctly, BUT this causes the table to be SMALLER THAN THE SCREEN for small tech trees from mods, meaning the tech tree is in a crumpled heap at the lower-left corner of the screen Having this be a separate table allows us to leave the TopTable as is (that is: auto-width to fit the scrollPane) leaving us the juicy small tech tree right in the center.
