Added Ecore_IMF module.

Added Ecore_IMF module. This module enables different input methods to be
used with Ecore. Input methods modules can be created using the Ecore_IMF
interface.
Added ecore_evas_window_get method to allow input methods to request
the window related to a given Ecore_Evas when available.
