Issue solved - Add sourcemap for webpack #61

[stablexbt]

Source map is added to webpack

• The Webpack devtools are set to generate sourcemap.
• 2/2 webpack function files were modified to add devtools functionalities.
• Errors will be displayed with line numbers of original files, hence easing down debugging.
• Devtool setting can be changed from "source-map" to "eval-source-map" for faster development and testing purposes.

@abhioncode nice job ! straight to the point :) . Do you think you can make the PR directly to the master branch ? v1.1.16 is an older one
