-- Fix duplicate figure Plot Probe bug

-- Don't disable Plot Probe GUI menu item in MainGUI when HRF checkbox is not checked. We want to keep PlotProbeGUI utility generic for any data not just HRF.
-- Removed some code from includes.m and PrintSystemInfo.m to try to improve Homer3 startup time. Identified in matlab profiler as slightly slowing things down during startup.
-- Get rid of matlab syntax warnings in PlotProbeGUI.m
