Better support for Browserify and Webpack

A new version of rollbar.js has been released, featuring updates that improve compatibility with Browserify and Webpack. The updated version is available both on the company's CDN and GitHub, along with examples demonstrating its integration with these tools. This release provides an alternative for users who prefer to incorporate rollbar.js through Browserify or Webpack instead of using the standard snippet, with contributions from @altano acknowledged for assistance in the update.
