Added a series of global variables to be used throughout the GUI.
This corresponds to one component of the patch_II file attached to https://gna.org/task/?6847 by Michael Bieri (https://gna.org/users/michaelbieri).
These include the global_setting list, the file_setting list, the sequencefile, and tables of results.
