Patch to genericize org-yank (6.21b)

[sand@blarg.net]

The org-yank function has special support for outline structures.  But
if you want the same behavior for something other than yank, you're
out of luck.  This patch (against 6.21b) moves the main functionality
into org-yank-generic, with yanking being just one particular entry
point.  (I use this to create a new entry point for a personal
clipboard-inserting command.)
