ParsefromID should include the element it is Parsing

[dshanske]

The documentation for ParsefromID states it only parses the children of the element. It should parse the element and its children.

Example, I tried to parse the events id on tantek.com and didn't get the surrounding h-feed. Having the base element would make it much more useful.

This has come up again in discussions of how to get a single h-entry in a feed of h-entrys
