…et because it's completely non-functional. Changed the exit dialog to use signals instead of global variables and switched to using relative paths for the ButtleOFX logo.

…directory if a QUrl was passed to it. Also removed file extension checks elsewhere, since this is covered in saveData().

…ave to stick to passing in absolute paths to buttleData.loadData().

… text entry bar.

…e workflow is a bit buggy still, will need a bit more work.

…me dir first by means of the new _buttleData.homeDir property and FileViewerDialog.folderModelFolder property, replaced FileViewerDialog.currentFolder with FileViewerDialog.currentFile, and changed the way the URL bar text is assigned.

…in MainWindow.qml, and exposed the text of the dialog as a property so it can be modified more easily.

…ttonClicked signal from ExitDialog.qml since it's always handled the same way (hide the ExitDialog), and set the ExitDialog to hide itself automatically when a button is clicked instead of having to do it manually when instanced.

Fixed up the interaction between the ExitDialog's and finderSaveGraph, we now pass a bool in signals from the ExitDialog's to trigger finderSaveGraph.show(). The bool indicates whether to create a new graph or quit the application.

… to be taken, and set buttleData.saveData() to use .toLocalFile() to turn URL's into proper paths.

…tDialog.qml is initialized to a default value, and we now send the filepath of the selected file in FileViewerDialog.qml with the buttonClicked() signal (cleaner since we don't need the extra property).

… fix it so that the current URL is displayed when the dialog is launched from the file menu, which is broken with this commit. On the upside, it now displays properly when the dialog is launched when the user hits the close button or hits Alt + F4 (haven't committed that bit of the code yet).

This just replaces the QMessageDialog's for the close event with our own. Todo: figure out how to make the dialogs modal.

… that the graph is only cleared when necessary, and made some wee cleanups.
