The edit-screen title field was single-line, so long titles scrolled off
one line instead of wrapping. Make it multi-line so it wraps and grows
vertically, matching the detail screen and Google Calendar.
A title is still one logical line: strip any newline the IME's Enter key
or a paste would introduce in setTitle, so no line break reaches the
provider's TITLE column.
