Two copies of same plugin can prevent either of them from working

[marick]

To reproduce:

% lein plugin install lein-midje 1.0.3
% lein plugin install lein-midje 1.0.4
% lein midje
That's not a task. Use "lein help" to list all tasks.

Deleting either of them lets the task be found:

% lein plugin uninstall lein-midje 1.0.3
% lein midje

Thanks; will definitely get this fixed for the next version.

This is caused by line 60 of bin/lein, but I'm not sure how to fix it. Need a hand from someone who's better at shell scripting.

Basically it's trying to remove duplicates, but the problem is that it steps through all user-level plugins and skips any of them that are detected as dupes. This would be fine if duplicates only occurred between user-level and dev-level plugins, but the user-level plugin list can include duplicates in itself. So when it sees lein-midje in there twice it doesn't let either entry through.
