Added the SimpitObserver class that will be used to remove the boost dependecy.
Use it as a static class, all methods and variables are static to avoid global variables :)
Updated the .gitignore file to ignore common Orbiter files
Also this cleans up 'git status' without using '-uno'
Changed main.cpp to send SimpitObserver the pointer to the SimpitManager
Removed all references using boost::bind and replaced them with the SimpitObserver method
Removed a #include to boost::bind in SimpitManager.h
Removed use of boost:thread in SerialInput, and replaced with standard Windows threading
Removed the boost entry from StdAfx.h
Removed final reference to boost in project which resided in the lib/include directories. Closes issue 2
Merge branch 'remove_boost' into develop
