JavaScript refactoring (#303)

* First commit integrating refactored JS code from Bruno Sampaio to remove reliance on Google Closure and support WebPack integration

* Resolving issues with failing tests

* Moving location of npm install call to match updated router_test.html

* Updating documentation with WebPack information

* Updating capitalisation of webpack as requested.

* Adjusting spacing for note block

* Updates to gulpfile, package and documentation addressing comments from @stof

* Setting correct permissions on js files imported from Bruon's work

* Correcting permissions, capitalisation, and version number

* Adding non-static method for route setting to simplify commonJS implementation

* Run a build prior to the JS test suite. Updated documentation.

* Switching Travis to use the same install and test commands as documented

* Updated gulpfile in an attempt to support PHP 5.3 on Travis

* Updated gulpfile removing another choke point for Travis on PHP 5.3

* Setting babel parameters in gulpfile to allow removal of .babelrc to prevent unexpected dependencies in projects

+Because the current test suite runs against the built javascript a build is automatically
