Renames AXNodeTextStyles to AXTextAttributes

This is purely a rename patch. It is in preparation for making AXRange
cabable of computing the text and its associate text attributes in a given range.
Text attributes do not only include style information, but may also contain document markers,
e.g. information about misspellings.
