Merge pull request #22 from kingtim/tooling-session

Use nrepl-current-tooling-session for ac-nrepl calls.

Trim leading and trailing whitespace from doc strings (fixes #23)

A bug in auto-complete (or popup) causes newlines to be inserted if

fixed, a nil return value was necessary in order to prevent the reported issue.
Add the class cache function to the end of nrepl-connected-hook

Whatever the cause of issue #24, it seems more correct to add this hook
function *after* `nrepl-enable-on-existing-clojure-buffers`.
