core: Add FeedItem class ()
Add transformation from legacy items to FeedItems, before transforming
items to the desired format. This allows using legacy bridges alongside
bridges that return FeedItems.

As discussed in , instead of throwing exceptions on invalid
parameters, add messages to the debug log instead

Add support for strings to setTimestamp(). If the provided timestamp
is a string, automatically try to parse it using strtotime().

This allows bridges to simply use `$item['timestamp'] = $timestamp;`
instead of `$item['timestamp'] = strtotime($timestamp);`

Support simple_html_dom_node as input paramter for setURI

Support simple_html_dom_node as input parameter for setContent
