deprecated functions: scatter_classic, quiver_classic, colorbar_classic

In June I asked if anyone was still using pcolor_classic ( I got no replies, so I have now removed it from svn.

Next: it looks like scatter_classic dates from the same era. Does anyone have any objections to its removal?

Two more deprecated functions are the original quiver and the original colorbar. These have been replaced more recently by new and much more capable versions (May-June of this year), but I am hoping that it is not too early to remove the originals. Does anyone still need old-style quiver and colorbar?
