Add bash-completion script for golo cli.
Move bash-completion to share directly in project top level folder to be more unix-y.
Add golo new command to golo bash completion script.
Fix to prevent completion from confusing the golo command with the golo subcommand.

Trying to use autocompletion for 'golo golo' would result in auto completion for the golo subcommand if you just tried to do auto completion for the golo command. COMPWORDS includes the top level command, so we just need to look for a special word from the 2nd indice instead of the first.
Add LICENSE to golo-bash-completion
Add autocomplete support for vanilla-golo script.
Add terminal completion section and short paragraph on setting up bash autocompletion.
Remove terminal-completion.asciidoc and move it into basics.asciidoc
Rename bash-completion folder to shell-completion and add @danielpetisme's zsh script.
Remove terminal-completion.asciidoc include from golo-guide.
Add golo-zsh-completion section to describe how to use.
