CRM-12757 - Upgrade open-flash-chart.swf

This is an untested / unreviewed import of the OFC-2 binary from:

http://joobi.co/latest-news/entry/jnews-8-1-x-security-release

I'm a little concerned that the size of the binary is markedly different than the old one (old: 280k, new: 150k). Are the using a different compressor/compiler? Have they disabled or replaced some features/functions?
