Update github plugin to work with current hub versions

Removes old completion setup that breaks with current _git and _hub completions.
Ruby is no longer required by hub; removes that test.
Does not define new completions for hub; they are now defined by hub itself.
Change the functions to use hub to create the repos on GitHub.
Add error checking to the functions.
Removes apparently-unused _github completion definition.

+#  github
+
+This plugin supports working with GitHub the command line. It provides a few things:
+
+* Sets up the `hub` wrapper and completions for the `git` command if you have `hub` installed.
+* Completion for the `github` Ruby gem.
+* Convenience functions for working with repos and URLs.
+
+###  Functions
+
+* `empty_gh` - Creates a new empty repo (with a `README.md`) and pushes it to GitHub
+* `new_gh` - Initializes an existing directory as a repo and pushes it to GitHub
+* `exist_gh` - Takes an existing repo and pushes it to GitHub
+* `git.io` - Shortens a URL using [git.io](http://git.io)
+
+
+##  Installation
+
+[Hub](http://github.com/github/hub) needs to be installed if you want to use it. On OS X with Homebrew, this can be done with `brew install hub`. The `hub` completion definition needs to be added to your `$FPATH` before initializing OMZ.
+
+The [`github` Ruby gem](http://github.com/defunkt/github-gem) needs to be installed if you want to use it.
+
+###  Configuration
+
+These settings affect `github`'s behavior.
+
+#### Environment variables
+
+* `$GITHUB_USER`
+* `$GITHUB_PASSWORD`
+
+#### Git configuration options
+
+* `github.user` - GitHub username for repo operations
+
+See `man hub` for more details.
+
+###  Homebrew installation note
+
+If you have installed `hub` using Homebrew, its completions may not be on your `$FPATH` if you are using the system `zsh`. Homebrew installs `zsh` completion definitions to `/usr/local/share/zsh/site-functions`, which on `$FPATH` for the Homebrew-installed `zsh`, but not for the system `zsh`. If you want it to work with the system `zsh`, add this to your `~/.zshrc` before it sources `oh-my-zsh.sh`.
+
+```zsh
+if (( ! ${fpath[(I)/usr/local/share/zsh/site-functions]} )); then
+  FPATH=/usr/local/share/zsh/site-functions:$FPATH
+fi
+```
