Importer and exporter overhaul, mega props duck. 

Exporter overhaul:
 * Add author information to export
 * Greater usage of slug identifiers
 * Don't export auto-drafts, spam comments, or edit lock/last meta keys
 * Inline documentation improvements
 * Remove filtering for now (@todo)
 * Bump WXR version to 1.1, but remain back compat in the importer

Importer overhaul (http://plugins.trac.wordpress.org/changeset/304249):
 * Use an XML parser where available (SimpleXML, XML Parser)
 * Proper import support for navigation menus
 * Many bug fixes, specifically improvements to category and custom taxonomy handling
 * Better author/user mapping

Fixes #5447 #5460 #7400 #7973 #8471 #9237 #10319 #11118 #11144 #11354 #11574 #12685 #13364 #13394 #13453 #13454 #13627 #14306 #14442 #14524 #14750 #15055 #15091 #15108.

See #15197.
