escape */ to *\/ in the inlined sourcemap to avoid ending the comment

[gustavnikolaj]

I had an application that stopped working whenever I added the debug flag in the middleware options.

Turned out it was because said source map included the string */ which would cause the browser to throw a SyntaxError when evaluating the prematurely closed comment.

SyntaxError: Unexpected token )

This is the problematic line: https://github.com/assetgraph/systemjs-asset-plugin/blob/master/asset-plugin.js#L58

My fix here breaks the regex that caused the problem, but I couldn't think of other ways to do this that wouldn't change the outcome. It could also be a comment in the inlined code.

How about using a single-line // ... comment instead?

I'm pretty printing the source map for debugging purposes, so there are newlines. Multiline comment is needed.
