Allow selection of values to load when selecting Load Config
When loading a configuration file in the GUI via "Load Configuration", allow selecting which values to load.
A dialog needs to be implemented which pops up when the menu item is clicked which asks:
- "Load Everything?"
- "Select what you want to laod"
- "Cancel"
- "Save current configuration"
Upon "Select what you want to load" an additional dialog should open, on top of the previous one, in which checkboxes for all available fields are presented. Initially all should be checked. Unchecking means that value won't be loaded into the GUI.
Both dialogs probably need to be displayed in their own frames, as the JOptionPane.show...Dialog closes when any option is selected. Research needs to be done here.
