Title: close #235 - rename observer .hpp -> .param

Refactoring of radiation observer setup.

- rename observer.hpp -> observer.param
- add Doxygen documentation
- add extensiv comments

@ax3l:
```bash
git mv ./src/picongpu/include/simulation_defines/param/observer.hpp ./src/picongpu/include/simulation_defines/param/observer.param
```
does not seem to result in a real renaming in git. (It's not file oriented.)
