Edit Decisions Menu

The Edit Decisions Menu allows the user to inspect, create and remove decision files inside the mod selected in the Start Menu. The user can:
 * 1) Create/remove folders
 * 2) Create/remove decision files
 * 3) Select a decision file to be edited in the Decision Menu

File list

 * The left-hand portion of the screen acts as a file explorer, pointing at the folder holding the mod files. Only folders and decision/policy files are shown
 * For each folder, the number of "elements", i.e. decision/policy files contained within, is shown
 * With DecisionsMenu-Delete.png the user can delete the selected entry, be it a folder or a file. Confirmation is asked if the folder/file is not empty
 * DecisionsMenu-FolderUp.png brings the user to the parent folder in the hierarchy, with the topmost folder being the one containing the mod itself
 * DecisionsMenu-NewFile.pngs the user to create a new decision file choosing from one of three types:
 * Decision file: the file name must end in "Decisions"
 * Narrative decision file: the file name must end in "NarrativeDecisions"
 * Policy file: the file name must end in "Policies"
 * DecisionsMenu-NewFolder.png allows the user to create a new folder
 * When a folder is selected, DecisionsMenu-FileOpen.png brings the user to its content
 * When a file is selected, DecisionsMenu-FileOpen.png becomes DecisionsMenu-FileSelect.png which allows the user to access the Decision Menu where the file content can be edited
