JSDC 0.86 : Important update!

Bugfixes. Bugfixes. Bugfixes.
0.86 consists almost entirely of bugfixes, and is a quite important update.
The case might even be that some might not have been able to get JSDC working at all, since there was a severe bug in the master-detail functionality, which simply didn't work unless one also hade a condition set!
Anyway, now it is a much better library. As usual, look at http://www.menialtools.com/GI_calculator.php for it flexing it's growing muscles...:-)
