and adapted classes using math to the new structure

* made loops comply with CodingStandard
* made constructor explicit

Not yet sure whether the WValueOperators namespace is the right way to do the non-member function implementation

[FIX] removed const, as integral types are returned as const by default. "-Wextra" option that will be introduced soon would complain about it

[CHANGE] Improved documentation and return types

- Moved GUI initialization to Kernel
- Integrated graphics engine into Kernel
- Integrated test Module into Kernel
- Added multithreading for Modules, graphics Engine and GUI
- Temporarily disabled WOptionHandler Code

[ADD] Some handy string manipulation helper functions. The reason why not using Boost's are in the flexibility and simplicity. And look on those unit tests :D.

- changed order of includes to match guidelines

- added osg headers to list of frozenset (lib headers) so that make stylecheck knows about them

[STYLE] Fixed style problems that were not detected on my computer because the linter died (see #83)

- now it compiles on Suse machines with older CMake

- added all OSG Modules explicitly to link list

- now using CMake module FindOSG* to search OpenSceneGraph paths

- added basic graphics engine
- added basic class stubs for Kernel, Modules

- added default messages

[CHANGE] zlib support for loading compressed NIfTI files is disabled for windows because we have problems with zlib there at the moment. See corresponding ticket in trac system.

[FIX] make stylechecker pass ... I will definitely create a box for money that has to be payed for forgetting "make cicheck" now!

* closes #9
* added getPosition functions and corresponding tests
