0.4.0: Square-brackets no more

This isn't a big release, but it is a breaking change.

As of 0.4.0 lein-try no longer supports square brackets ([ ]) as a means of specifying dependency name/version pairs. Square brackets are simply too wonky in ZSH and BASH to continue risking that users encounter odd behavior because of them. See #16 for more info.

Where you used to say: lein try [clj-time "0.1.0"]
You must now say: lein try clj-time "0.1.0"

To upgrade, modify your ~/.lein/profiles.clj to include [lein-try "0.4.0"] like so:

{:user {:plugins [ ;; ...
                  [lein-try "0.4.0"]
                  ; ...
                  ]}}
