[FEATURE] Show "Open Document..." action when right clicking certain

files in the browser, allowing them to be opened with the default application for that file type E.g. PDFs will open with the default PDF viewer. Works with PDF, ODS, XLS(X), CSV, TXT, PNG, JPEG, TIFF, SVG (other types will likely need more work, since they aren't currently shown in the browser)
