chips: suggested contacts

This change adds support for custom suggested contacts (not associated/present in
the contacts provider) in BaseRecipientAdapter.

Basically an implementor MUST overload BaseRecipientAdapter#loadSuggestedEntries
and return a set of SuggestionEntry. This class also should react to onAddSuggestion
and onDeleteSuggestion methods, invoked when the user request add/delete the
suggested contact.
