[Patch] Add duplicate search to keypress events instead of blur

[Dan G. Switzer, II]

I modded this plug-in to support duplicate search as the user's typing--which is a bit more effective and intuitive. To do this, I changed the events to use the keypress and keydown events. In order to improve performance, I use a debounce() technique to make sure that the AJAX call is only called after 1s of delay after the last key press.

I also set the tabindex to the elements in the suggestions to 32767 so that pressing [TAB] takes you to the next Trac field.

I'm attaching a patch of my changes.

Diff patch that implements efficient keypress checking

[Ryan J Ollos]

Thank you for the patch. A couple of issues:

1. The patch has no header, so I had to apply it manually.
2. After applying to patch, I get a javascript error debounce is not a function.

I'm going to apply the part of the patch that makes the tab move to the next input field. If you could regenerate the patch with a header so that I can apply it directly, I'd appreciate that.
