Update ZeroClipboard.js

- the embed tag didn't exist in xhtml, in html5 it returned, but different than in all Adobe's erroneous advices. It's a huge hoax that browsers needs it to play flash, in fact: if the object is correct (valid), then it works BETTER without!
- classid parameter doesn't exist neither
- if you replace that last one for  type="application/x-shockwave-flash" it will work better...
- ...but only if the objects "src" is now named "data"
- height and width are deprecated or invalid in HTML5, so I changed it for -in this situation- more usefull CSS
- allowScriptAccess is a permission thing and so belongs at the top of the param's
- scale I changed to "noscale" as it will leave content alone and cropping may occur.
- bgcolor #fff + wmode transparent is a conflict
- flashvars works better as FlashVars (in older players)
