added version number

[borkdude]

Added a version var to initialization.clj (is this the most logical place for it to exist?) and added it to the default-init-code to print like this (in line with the Clojure version number):

macbookair-michiel:bin Borkdude$ ./reply.sh
REPL-y 2.0.0-SNAPSHOT
Clojure 1.3.0
Exit: Control+D or (exit) or (quit)
Commands: (user/help)
Docs: (doc function-name-here)
(find-doc "part-of-name-here")
Source: (source function-name-here)
(user/sourcery function-name-here)
Javadoc: (javadoc java-object-or-class-here)
Examples from clojuredocs.org: [clojuredocs or cdoc](user/clojuredocs name-here)
(user/clojuredocs "ns-here" "name-here")

Cool, I like where this is going. I'd want the version to be the same one from the project.clj, though. Maybe that means having a src/reply/version.clj file with the authoritative version number that gets read in both places?

Thanks for doing this!
