Travis CI and Documentation Generation Improvements

* Use docker images from docker hub instead of building them on Travis
* Fix doxygen warnings for Markdown Files
* Modify Travis build matrix to include stages and additional jobs
* Add doxygen2jsdoc submodule
* Add doxyport submodule
* Remove duplicated code in doxy/node directory
* Generate documentation for each language in Travis
