1. provide automatic relocation of important links in items that are imported or synced to clones

2. provide framework for custom curl request bodies using custom/non-standard request methods. This was a real nightmare because curl doesn't actually let you specify a string to send as the request body (except when doing POST). You have to treat it as a file upload using a custom file handler function which provides the actual content in chunks as if it were buffered I/O.
3. item_store and item_store_update now return the item that was stored
