Clearing Text Selects No Value Option (Enhancement)

[GoogleCodeExporter]

Just an enhancement that I'm using. Thanks for the great control.

Use empty value option at the top of drop downs that are optional (with or 
without some helper text - e.g., "Select one of the following..."). The changes 
below the selection to be reset to the first non-value option by clearing the 
text and tabbing off the drop down (currently it reverts to the previously 
selected value and isn't as key board only friendly).

Enhancement applies to ufd 0.6.

1. filter method (line 413) - passing search text along:

self.updateOnTimeout = setTimeout(function() { screenUpdate(searchText); }, 
self.options.delayYield); 

2. filter screenUpdate function (line 417):

var screenUpdate = function(searchText) {   

3. filter screenUpdate function (line 439):

if (!oldActiveHidden && active.length && self.trie.matches.length && 
(searchText != "" || self.selectbox.get(0).options[0].value != "")) {

Yep might be nice, although how is this done on the native element underneath? 
Is it assuming that the 0-th item is non-selectable?

For the native control, it just assumes the 0-th element is the "none selected" 
option (e.g., <option value="">Select an item...</option>) and then my server 
side validation on the post verifies that there is a value for the select list.
