title: Load fns into lein repl
body: <p>Hi I have some helper fns I want to load into the user ns for a lein repl on startup across all my projects.</p>
  
  <p>What's the recommended way to do this as lein plugin?</p>
  
  <p>Failing that I tried to make a ~/lein/user.clj and to my surprise that did't work? $Project/user.clj works fine but I don't want to copy to each project.</p>
