MAke HTML Decode regex non greedy

Using the current master HEAD, I had an issue decoding strings which contained multiple HTML entity codes e.g. '&#39;192.168.0.1&#39;'

I tracked the issue down to a malfunctioning regex which was matching the whole string between the first and last entity in the string. Adding a '?' to make the regex non-greedy restored functionality to the _fnHtmlDecode function and resolved the issue.
