Boot task

[podviaznikov]

Hi,

I took most of your code and create boot task: https://github.com/hashobject/boot-s3/. Maybe you can create s3 library that can be used in both lein and boot plugins?
In that way I'll just use your library and not copy code.

Btw, your code worked great. I really appreciate that you implemented check if file already exists in S3.
