Hiding doesn't work right yet. Click a thumbnail and the text disappears,
but the border between widgets doesn't move to the left side.
I tried using a Gtk::Expander, but couldn't get it to expand horizontally.
Label initially says "Destination path for the first selected image appears here"
so the feature is discoverable. Select a file and it shows the destination path
that would be used if it is the first file to be processed and the file does
not already exist. Label is updated as the template is edited, so you can see the
effect of the edits. If "Save to folder" is selected, the previewed path uses
that folder.
Replaces the following deprecated Gtk classes throughout the codebase by their non-deprecated counterparts. Style, HBox, VBox, HPaned, VPaned, HScrollbar, VScrollbar, VSeparator, HSeparator, Stock, Table, VScale and HScale.
Improvement to the Batch Queue:
- Start Queue/Stop Queue checkboxes replaced with one swith.
- It is now immediately clear whether the queue is running or not.
- The queue is visually stopped once it is empty.
- String keys fixed to use BATCHQUEUE_ prefix instead of FILEBROWSER_.
