Remove filterAttributes.js

This is no longer needed because of https://github.com/facebook/react/commit/089a494a1f0cc1892f1525fd746bac10c5a55175

mutateHTMLNodeWithMarkup.js was the only one using it.

Remove filterAttributes.js
Merge pull request #1491 from naturalatlas/itemscope

Added support for itemscope, itemtype, itemprop attributes.
Add hasOwnProperty checks where appropriate

For boolean-like objects, I've added hasOwnProperty checks in addition to the existing truthiness check even though for most of these dicts, we leave out false keys instead of setting them explicitly to false.

In DOMPropertyOperations, we don't need to check hasOwnProperty if the property is in isStandardName because (with the exception of getPossibleStandardName) the dicts on DOMProperty will now be consistently populated with every valid attribute.
Remove references to autoflow

Most references were removed in 6e59561; this should be the last.
