file system model: Add batched insertion

Browse Source 
Add a batched version of gtk_file_system_model_add_and_query_file
that takes a list of files and avoids resorting the model for each
individual insertion. The querying is still done one-file-at-a-time,
so more optimization is certainly possible.
