REDUCEConfigDialog: Make the second column of the command grid pane wider (and fixed width) to accommodate the larger font used on Linux. Fix commandRootDirDCButtonAction to match fcButtonAction. REDUCEConfiguration: Change the default Linux configuration to use the search path and not check the command pathname, which makes it easier to transition from the previous defaults.
