Add name of the Plugin as __doc__

As most plugins use the name as a description of the plugin
the name-value essentially acts as a description field of the
Plugin. Hence I decided to actually expose it as such.

vapoursynth/vapoursynth,Kamekameha/vapoursynth,Kamekameha/vapoursynth,Kamekameha/vapoursynth,vapoursynth/vapoursynth,vapoursynth/vapoursynth,vapoursynth/vapoursynth,Kamekameha/vapoursynth
