Merge pull request #289 from mdmoss/master

Update README with correct erlang version information
Boss executable
boss apps can be included in the deps dir. They are compiled the boss way.

I'm afraid my OCD also fixed indentation inadvertently.

With this commit, new projects can add to their deps directory a CB app, such as cb_admin.

It will be properly compiled (the Boss way™).

For use as a dependency to a main app :

- in rebar :
```erlang
{deps, [
  {boss, ".*", {git, "git://github.com/evanmiller/ChicagoBoss.git", "HEAD"}},
  {cb_admin, ".*", {git, "git://github.com/evanmiller/cb_admin.git", "HEAD"}}
]}.
```

- in boss.config:
```erlang
{cb_admin, [
    {path, "./deps/cb_admin"},
    {allow_ip_blocks, ["127.0.0.1"]},
    {base_url, "/admin"}
]}
```

If you want to use it with an existing project, get the skel/priv/rebar/boss_plugin.erl from ChicagoBoss, et overwrite <your app>/priv/rebar/boss_plugin.erl
