Allow setting the query without doing "getSuggestions"

[nwalke]

I purpose something like:
setQueryWithoutFetch: function(query) {
this.inputView.setQuery(query);
this.inputView.setInputValue(query);
this._clearHint();
this._clearSuggestions();
}

I am also after this feature. This is a must when binding with knockoutjs or similar.

This would be as easy as replicating the "setQuery" functionality and just not calling "this._getSuggestions();"

Should get resolved with #646 gets resolved.
