Surround the deploy process in a timeout.

Hi there, great work! I think webistrano is a neat solution. I've got a few suggestions for future features that you can take or leave as you will. This is one of them... :)

Sometimes the deploy fails... and sometimes it sits there spinning endlessly. (see http://rubyglasses.blogspot.com/2009/12/getting-webistrano-to-deploy-under.html for an example)

It'd be really nice if you could optionally surround the deploy process with a timeout... just in case.

Cheers, Taryn
