Generate source maps

[duncanbeevers]

• Activated by the gulp sourceMap boolean.
• Won't try to generate sourceMaps for handlebars versions < 3
• Strips path information, only preserves filename.

Closes #50

Regarding path stripping, this issue is open about absolute resourcePath in webpack. If something more relative-y comes along, it might makes sense to jump ship to that.

Sweet! I haven't tried it, but how does debugging work? Currently I can put a breakpoint in the compiled template, does something like that work if using sourcemaps?

@duncanbeevers, Thanks for the contribution. Can you add some docs to the README file explaining this new option?

I'm going to close this since it has seen no movement. Reopen if you want it to get merge in!
