Title: Added in_path? utility method in utils.rb

In response to this issue:
https://github.com/mxcl/homebrew/issues/8801

This makes it so that there is a standard option for figuring finding whether a program is in path without having to do your own `which -s` formulation. After looking at all the instances (and variations) on `which` in utils.rb, this seemed like it was useful.
