Title: Allow passing custom sourceContent (e.g., coffee-script source) to inline-source-map.

Currently browser-pack uses row.source as sourceContent, it works fine for javascript, but makes little sense for transpiled languages. In order to map the bundled code to the original source(e.g., coffee-script source), we need a way to pass it to inline-source-map.
