Title: Fix #786 ARC error when importing RKXMLParserXMLReader

https://github.com/RestKit/RestKit/issues/786
Importing RKXMLParserXMLReader in an ARC project cause following compiler error .
```
XMLReader.h: Pointer to non-const type 'NSError *' with no explicit ownership
```
Fixed by importing XMLReader in .m instead of .h.
