Windows include leak

[iondune]

Silly windows.h library macros are leaking somewhere. For example, in CWindowManager.h, there is a CreateWindow undef. Find the source and add undefines there (or better yet, remove the offending include).

Some work was done to resolve this but there appear to be some remaining issues.

[iondune]

Log class is now in a .cpp as of 0e3e75b, moving the #undef out of ionWindow. Still need an undef in ionApplication for SimpleIni include, but this could be fixed by wrapping SimpleIni (and other serialization classes).
