Update source-map to last patch version (0.1.43) #5411
Major bugs have been fixed in source-map 0.1.41. I can't use source maps generated by Webpack with 0.1.40, but 0.1.41 is working fine. Meteor should update source-map to the last patched revision.
This is a major blocker to the Webpack compiler because until then, we have no source map.
