Bug fix to self closing script tag, prevents assets loading

Have modified the script tag to not be self closing (like below)

    <script src="live.js"></script>
    
    
Previously the script tag was defined in a self closing style. Which unfortunately is not valid html, and as a result chrome (v29) and safari (v6.03) wouldn't load any assets after the point where live.js was inserted. Although live.js did load. This bug surprised me, i thought their (safari/chrome) parsers would be more robust
