IETANKS-55, IETANKS-56: Starting Tornado and Jetty

* Added ieTanks-* components
* Starting tornado (assumed it's installed)
* Minor refactoring
Personally I have python 2.7.3 and twisted also works for me so I don't know if this is a good idea to "bind" to python3 - for me it is no problem because I also have python 3 but I do not know about other ppl.
