richedit: Use ITextHost interface in ME_LinkNotify.

[Dylan Smith]

Using the ITextHost interface allows this notification to be received for
windowless richedit controls.  Windowed richedit conrols have an ITextHost
implementation that will fill in hwndFrom and idFrom, but these should
probably be initialized to 0 for windowless richedit controls.
