Update ruby version for a given project

Before you update via Capistrano remotely you must make some changes locally first.
- Update the projects .ruby-version file
- Update rbenv / ruby so that the required version is available to install (if needed).
  - For Linux:
```
cd ~/.rbenv/plugins/ruby-build/
git pull
```
  - For Mac: (https://github.com/sstephenson/rbenv#homebrew-on-mac-os-x)
```
brew update
brew install rbenv ruby-build
```
- Update ruby
```
cd [into project directory]
rbenv install  [ will automatically install the version listed in your file: .ruby-version]
```
- Install bundler:
```
gem install bundler
rbenv rehash
bundle install
```
Push changes to your repository.
Now you can update your applications remote installations of rbenv & ruby:
```
cap [environment] rbenv:update
cap [environment] rbenv:setup
```
Continue on with normal deployment.
