Brian Palmer dc142ca33f switch to the speex codec for the flash recording widget
fixes CNVS-19888

The most recent version of Flash has a critical bug that causes the default
NellyMoser codec to play back at high speed
https://bugbase.adobe.com/index.cfm?event=selectBug&CFGRIDKEY=3970924

I wasn't able to fix the issue by changing NellyMoser sample rate. Switching to
the (more modern) Speex codec fixes the issue. There might be a slight decrease
in sound quality, since Speex sampling is 16khz, vs the 22khz we were using for
NellyMoser. On the other hand, the Speex codec is more optimized for speech,
which is what most of our recorded video is.

This also pulls in a new build of our KRecord.swf widget which enables
soundcodec and soundrate options.

test plan: without this commit, recording webcam video/audio will play back the
preview at high speed. with this commit, it should play back at the correct
speed. the video/audio should also save and play back later as expected.
