Everything builds in one run! (or at least should)

I've added libnpa as a submodule for this project, since it has some dependancy issues if there isn't a folder named "libnpa" one directory higher then libnpengine.

- Change in .gitmodules will probably have to be changed to proper repo instread of my fork (which is modified as well for the sake of nice one command builds.

- Boost timers didn't compile out of box so I switched them with STL eqivalents. I'm not sure if they work how intended though.
