Rewrite of the sliders plugin wich is aviable in the sdk as a master plugin (first release because there are two issues I do want to solve in the next version)

There two or three differences between the custom plugin and this version (due to the nature of the plugin):

1. You can provide a group name to the slider bar, wich will also be displayed inside the master plugin
2. You can also give it an extra color
3. The whole bar (no only the drag icon) can be used to drag,
4. Morph Envelopes have a minimum / maximum value of -100% to 100% per deault
5. No Slider Tool for adjustment needed

Current issues
1. Object Replacement / Surface Envelopes can result in loosing reference
2. Random Crasehs when quitting lightwave (Clear scene works)
