Ralf Ramsauer 49a5b88f6c Big rewrite of several things
- Data type Token changed from uint64_t to std::string
- Added new class "Request" that describes a JSON TCP request
- Classes may now throw Responses for proper error handling
- Removed JSON parsing from Logic
- proper Error handling everywhere
- Many small fixes
- removed unnecessary includes
- removed using namespace std everywhere
