core: Add FeedItem class (#940)
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 #940, 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
