iOS: Fix a crash in HandyFTP, an additional check I put in for
dw_window_get_text() made it return NULL on 0 length strings.
Also fix main thread API check warnings for calling updateMenu:
by creating a safeCall: method to do it from any thread.
Add code to cleanup after splitbar and notebook controls.
