Volker Ruppert 0d425037df Improved plugin type detection at Bochs startup. 
- 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).
