fix "name": "twitter-bootstrap" (v1 & v2)

fix for https://github.com/jsdelivr/api/issues/50 where expected API call is http://api.jsdelivr.com/v1/bootstrap/libraries?name=bootstrap but http://api.jsdelivr.com/v1/bootstrap/libraries?name=twitter-bootstrap is actual.
v1: keeps both for compatibility.  It clones, fixes, then prepends. (live)
v2 (of both api & api-sync): only renames (commented out)
todo: warn not to use "twitter-bootstrap"
[Array.slice()](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/slice) seems to do only a 'shallow copy'.  IIRC some code I copy-pasted didn't work.  This worked, so I left it & moved on.

I'm open to PR for provable working changes. :)
