[Feature request]: Namespace / prefix for fabric aliases

[superclarkk]

What do you need?

Being brand new to the project, this is a very humble request, not meaning to step on Daniel's toes if there are reasons why it's not a good idea. However, there are already 103 patterns, and counting. Although they are amazing, speaking as a linux/bash user, they do tend to pollute the environment. Wouldn't it be better if they all had a common prefix? fab_ seems like a perfect one to me, considering fabric is "fab(ulous)". This would have the added bonus of making tab completion much more useful, because fab_ followed by a would list all the fabric commands/patterns.
