Add QSortFilterProxyModel to ResourceBrowser
In order to enable a search bar in the resource browser, add an optional QSortFilterProxyModel in addition to the existing model.
- Use the json config to control whether the search bar is on
- If the search bar is enabled, the QSortFilterProxyModel will filter the default model, and a text-item search bar is added to the widget.
Leaning towards enabling the search bar by default in the main resource panel.
