Fix stdint.hpp for <=VC9.
Fix intrusive_ptr template init on windows. The second template argument should probably be removed if its not neccesary for other platforms. I did not find boost documentation for what the second argument actually does, but in the meanwhile ifdeffed so that builds on windows (yes its ugly). Fixes #198 (with a semi hack).
CMake continued: Try to detect g++, clang, windows and osx and setup appropriate defines and build flags. Improve so that each setup can define platform, boost and ssl libs. I tried to copy everything that I could from the scons scripts, probably some of this can be removed (might be automated from cmake already), left todo:s for that. Added building simple examples, more to follow. NOTE: This has only been tested on windows.
