Merge pull request #7 from drewr/master

Optional bootclasspath to address issue #6
Release 0.3.0
Added ability to set {:bin {:bin-path "/foo/bar"}} in project.clj or profiles.clj, so that after creating a binary, a second copy is made and set executable, in a directory that you have presumably added to your path. This kinda emulates how the go command handles golang binaries, which can be handy.
Added docs for :bin-path option
Forget to update the example when I updated the docs.
Tweak README.markdown formatting.
Fix indentation.
Rewrite stuff with fs and inc version.
