JWPlayer bookmarklet code was incorrectly specifying the pseudostreaming url queryString as {start} instead of ${start}. (Or perhaps, this was back when we used an older version of FP? or something else? idk - it's been there since 2011...)

* fixing sherd.js
* patching flowplayer.js to correct the queryString
Merge branch 'master' of git.ccnmtl.columbia.edu:sherdjs into develop
