Update manifest

I am getting warnings from ```bundler``` when I try to install ```knife-solo``` from ```master```:

```
knife-solo at /Users/akhkharu/.rvm/gems/ruby-2.0.0-p247@chef-teamcity/bundler/gems/knife-solo-3be7d96047e2 did not have a valid gemspec.
This prevents bundler from installing bins or native extensions, but that may not affect its functionality.
The validation message from Rubygems was:

This update should fix them.
