/**
 * A dialog to manipulate the project's files.
 * The dialog allows the user to add source files to the current project, or
 * remove files from it. The main widget of the dialog is a list view, that
 * displays all files currently in the project. When files are added or
 * removed, this list view is updated. The project, however, is only modified
 * if the user closes the dialog using the "OK" button.
 * Since searches through a list view are very slow, the class also maintains
 * a QDict object, that connects file names with their respective list items.
 * This dictionary is used to ensure duplicated items are not added to the
 * list.
