Re: Change sourceMappingURL comment syntax to avoid IE JS conditional compilation issues

Eddy, can't the browser support both but issue an extra deprecation warning
for using the @ version? As mentioned before there are already many tools
and sources that rely on the @ version. No sense breaking them just like
that. The console warning should help devs migrate to the new spec.

Also, pushing that patch right now, without a new version of the spec at
all, effectively means killing any source maps for firefox :p
