Add platform specific builds and zip tasks (#486)

* Add platform specific folders to dist folder

* Remove gulp hacks

* Add platform specific bundling

dev and dist tasks now build into platform-specific folders within the `dist` folder.

Added tasks `gulp zip` and `gulp dist`.

`zip` builds the platform-specific folders into platform-specific bundles within the `dist` folder.

`dist` builds and then zips all at once.

* Fix chrome bundle zipping

* Fix broken reference in eth warning

* Fix but where web3.eth.accounts are not available in firefox.

* Bump changelog
