[OpenWalnut-Dev] Switching to C++11

[Sebastian Eichelbaum]

Hi List,

I have pushed several changes (Release Branch) to make OW compile with 
--std=c++11 compiler flag. The issues where mainly related to implicit casts of 
shared_ptr to bools (something like "dataValid = ( dataSet )"). I changed this 
to "dataValid = ( dataSet != NULL )". Although this is not the C++11 way (we 
should use nullptr), it keeps compatibility with c++98 for now, as we are not 
yet sure if everything is fine on OSX (Linux + Windows was tested by me. Works 
with Clang).

I would like to ask you to compile OW again. Please also test GCC and OSX.

If everything is fine, we stick with c++11.

Best
Sebastian
