Comment 2 for bug 1101771

The HintedEntry does not have a built-in clear icon. Only the Searchbar class has one. Yet some people might want to use it in a normal HintedEntry, so maybe we could put the clear icon into the HintedEntry class. I just think it would be more convenient.

The constructor could look like this for compatibility:

 public HintedEntry (string hint_string, bool has_clear_icon = false);
