	* Fix for "44222 task summary entry widget not i18ned". The following
	files are changed.

	* gal/gal/e-table/e-cell-text.c: Lots of changes for i18n
	selection/input support. Added these functions for input method support.

	(e_cell_text_preedit_changed_cb)
	(e_cell_text_commit_cb)
	(e_cell_text_retrieve_surrounding_cb)
	(e_cell_text_delete_surrounding_cb)

	(layout_with_preedit) This function inserts the preedit string
	with the right attribs to the layout text.

	selected row/col. Also display the cursor at the end of preedit text.

	Disconnect when not in editing mode. Also a special flag to see
	when Enter key pressed in preedit mode, the text is committed only
	not a new row is created. This woks in conjunction with the changes
	made in the eti_event in e-table-item.c file and e-cell.h.

	do not delete the selection.
