add pre/post-save hooks...

add pre/post-save hooks - `ContentsManager.pre_save_hook` runs on the path and model with content - `FileContentsManager.post_save_hook` runs on the filesystem path and model without content - use pre_save_hook for things like stripping output - use post_save_hook for things like nbconvert --to python
