No new tests. This patch doesn't introduce any change of new functionality. It prepares for
additional changes which will inlude tests.

On OS X, alternative dictation results need to be stored as document markers. This patch introduces
following changes to achieve this:
1. Added DictationMarkDetails to store non-string type maker detail.
2. Introduce DictationCommand, which is similor to TypingCommand, but allows inserting text with
  attached markers.
3. Added Editor::insertDictatedText as interaface to WebKit and WebKit2.
4. Added struct DictationAlternative to pass dictation related info from WebKit to WebCore.

Several fragments of code in TypingCommand can be also used by DictationCommand. So this patch
introduced a new class, TextInsertionBaseCommand. It's a subclass of CompositeEditCommmand, and
base class of both TypingCommand and DictationCommand.

This patch also extends InsertTextCommand class. Its constructor will take an TextInsertionMarkerSupplier
object. After text is inserted to a node, InsertTextCommand would give marker supplier a chance to
add document markers to the inserted text.
