- Fixed 'console' plugin causing delete_timer error when it fails to load, due to uninitialized variable.
* Renamed plugin.def to sample.def and added 'sample' plugin exports into it, as it's purpose is nothing than a sample right now.
- Also added .def files for 'gui' and 'pid' plugins as MSVC does not export everything automatically and missing event export cause the plugins silently failing.
- Added VS6, VS8 and VS9 projects for compiling plug-ins, which can be used on Windows.
* The plug-in system will now report, if it cannot import an event function.
