- Added special mode to all plugin entry functions that returns the plugin type. - The plugins search function now temporarily loads all available plugins and reads the plugin type using the new mode PLUGIN_PROBE. - Added "loadtype" to the plugin structure to store the type used for plugin loading (currently only the voodoo plugin provides two types).
