Performance optimizations:
- All synchronous connections are finalized in the worker thread in order to
reduce amount of switches between the thread-pool and event loop
- Even cancelation on socket that does not has pending events does not cause
breaking of main event loop

Performance imrpovements - moved from dynamic typed settings system to static "cached" one
for performance critical parts

Performance improvments:
- full-copy function replaced with callback that shares its object
- introduced callable object that can handle big handlers efficiently with 0 copy overhead

- Added callback class - function with shared semantics
- Switched to use of callback in all internal classes

This may workaround nasty CMake 2.6 bug

Attempt to fix msvc bug #3023329

Added better range checks for to/from number conversions so if
converting integer type that can't be represented as double would throw

Added specialization for all integer and floating types

Fixed number presision issues
