Simple and crude tab-completion for pattern names

[residualmind]

Before I discovered that all these nice aliases are being created, while I was playing with the existing patterns, I really wanted a shell tab completion for the pattern names. This is a very simple way of achieving it:

Running

complete -W "$(ls ~/.config/fabric/patterns)" fabric

gives you a very simple but effective TAB-completion for pattern names in bash and zsh.

Is this against the philosophy of using aliases? If not, it could be added to the bootstrap file, I'd be happy to create a PR.
