* Moved plugin API event constants to a separate header agsplugin_evts.h.
Engine should not include whole plugin API, this is unnecessary, and may
create naming conflicts.
* Moved SimulateMouseClick to mouse.cpp.
* Minor cleanup in agsplugin.cpp

The idea is to have similar interface internally in the engine, without having to refer to the
plugin's API; at least to keep things consistent with the rest of interfaces for now.
(The whole engine interface system may need to be reorganized.)
* Renamed existing ICCObjectReader to ICCObjectCollectionReader, an interface that supports
multiple object types.
* ICCObjectReader is now an internal engine's alias for plugin's IAGSManagedObjectReader
(but it may be used for the internal purposes too if a need arises).
* Moved PluginObjectReader declaration, save 1 small h/cpp pair.
* Store pluginReaders in a std::vector, remove MAX_PLUGIN_OBJECT_READERS as redundant.
