[PATCH 2/5] editor: Support deleting text in preedit_string

[Jan Arne Petersen]

From: Jan Arne Petersen <jpetersen at openismus.com>

Delete text marked with wl_text_input::delete_surrounding_text on
preedit_string event. When text is explicitly marked with
delete_surrounding_text do not delete selected text.
