taxonomy_select none option fix

[adamcapriola]

I have a taxonomy with numeric terms — 0, 1, 2, 3, etc... — and the taxonomy_select option output was looking like this:

<option value="" selected="selected">None</option>
<option value="0" selected="selected">0</option>
<option value="1">1</option>

Doing a strict comparison seems to fix the issue and only None gets selected. I can then select the 0 value and it is saved and selected correctly too.
