update project to fit webpack2

[CntChen]

When using this plugin with webpack2.2.1, an error accoour:

TypeError: Cannot read property 'hasOwnProperty' of undefined
 .../string-replace-webpack-plugin/loader.js:12:29)

This plugin add custom propertie options to webpack compiler object. but webpack 2 no longer allows custom properties in configuration.

So I use StringReplacePlugin static property REPLACE_OPTIONS to store plugin's options and solve this error.

@jamesandersen this would be great to have in since I am running into the same issues in Webpack 2.2.1

@CntChen thanks for the PR. @CntChen and @josephliccini you should find the new version on NPM now.
