This library used to be provided by HXCPP, but it was removed in version
3.4.185. Fortunately, it doesn't seem to be necessary, so this commit
stops Lime from attempting to link with it.
When building a Lime application in debug mode on Windows, the console
subsystem is used and Windows looks for a 'main' function. However, the
Main.cpp file used when linking statically always defines a 'WinMain'
function regardless of whether the application is being built in debug
mode.
This commit adds an additional check in the Main.cpp that defines a
'main' function instead of 'WinMain' when building in debug mode.
