Adding OTP release handling on riakhttpc application

[edwardt]

It will be nice to add OTP release handling, thought this is an application library. But the versioning and packaging as such avoid copying the beam files everywhere if someone wants to integrate in their projects.

Here is the reltool.config (Erlang R15+ only) that I tested to use and it seems to generate the release under lib with the dependencies lib which can be further packaged for integration. There are some sections that are not required (like all of those overlay, booting up etc) because it is a library instead of a full blown node, but guess it is just a start. Please improve upon if decided to make the project OTP release handling friendly.

reltool.config:

       {lib_dirs, []},
