Source/JavaScriptCore:
Added new dtoa library at http://code.google.com/p/double-conversion/.
Replaced old call to dtoa. The new library is much faster than the old one.
We still use the old dtoa for some stuff in WebCore as well as the old strtod,
but we can phase these out eventually as well.
