Description

This PR addresses a couple of issues with source maps:

• uses correct file names (fixesSpecify inputFileName for javascript-obfuscator 0.17.0 #13)
• is chainable with other plugins such as UglifyJS and Babel
• prevents plugins such asgulp-header from prepending to the source maps as well as the code

Because ofjavascript-obfuscator/javascript-obfuscator#276, we can now usegulp-sourcemaps instead of throwing the source map to the stream! 😄

Backwards compatibility

As before, ifgulp-sourcemaps is not used and obfuscator'ssourceMap option is set totrue, a.map file will be thrown to Gulp stream.

gulp.src('file.js').pipe(javascriptObfuscator({compact:true,sourceMap:true})).pipe(gulp.dest('dist'));

NOTE: The old method is not recommended for new projects, for the following reasons:

1. Any gulp plugin that is chained after gulp-javascript-obfuscator (e.g.gulp-header to prepend a banner to the output file) will be applied onboth the obfuscated.js file and its.map file.

2. You will not be able to chain any other plugins to the task without loosing its own sourcemap file.
