Subject: [E-devel] [patch][elementary] access - add activate callback

till now, accessibility has used ecore_x_mouse_*_send(). the patch has
activate callback which takes place of the ecore_x_mouse_*_send() stuff.
if the access module is enabled and 'double tap' is detected, elm_win
will
receive ECORE_X_ATOM_E_ILLUME_ACCESS_CONTROL message with
ECORE_X_ATOME_E_ILLUME_ACCESS_ACTION_ACTIVATE and call the activate
callback for the accessibility. that's it.
