get_app_info
Description:
public bool get_app_info (string uri, string name, out string exec, out uint count, out time_t stamp) throws BookmarkFileError
Warning: get_app_info is deprecated since 2.66. Use get_application_info.
Gets the registration information of app_name for the bookmark for uri.
Use get_application_info instead, as `time_t` is deprecated due to the year 2038 problem.
See set_application_info for more information about the returned data.
The string returned in app_exec must be freed.
In the event the URI cannot be found, false is returned and throws is set 
      to g_bookmark_file_error_uri_not_found. In the event that no application with name app_name has 
      registered a bookmark for uri, false is returned and error is set to 
        g_bookmark_file_error_app_not_registered. In the event that unquoting the command line fails, an error of the 
      g_shell_error domain is set and false is returned.
