[Patch] The reinstall timer breaks footnoterefs (asciidoc.js)

[GoogleCodeExporter]

If the asciidoc.footnotes() function is called twice (such as if the reinstall 
timer is triggered), then all footnoterefs are renumbered to 'undefined' and 
broken. The attached patch solves this by only renumbering footnoterefs when a 
valid number is found for them:
