[2.0] Paredit inconsistencies

[PEZ]

Paredit behaves slightly different between the editor and the REPL window. It will sort itself out when we replace the editor Paredit with our shiny new one, but anyway.

Here are two things that the editor Paredit does better than the new one, IMO:

1. Wrap-around parens (), works in the editor, not in the REPL Window.
2. Wrap-around other things work, but in the REPL window they move the cursor next to the closing bracket, in the editor the cursor moves the opening bracket.

The new paredit does some things better than the old one. Here's one:

1. Wrap around with a selection wraps the selection. (The old paredit wraps only the first form in the selection.)

Also, when wrapping a selection, new paredit keeps the selection, but shrinks it one char from the right. I think it is reasonable to just scrap the selection after wrapping.
