Restructured project to version builds and move CSS into src.

* Added a new version implementation to the build. The build task now triggers
  an increment to the build version.
* Reconfigured the war plugin to filter source files and replace the @version@
  token with the project version and to rename css and js files to include the
  version number in the filename.
