Title: Rework dependency syntax

This set of changes introduces a [new
syntax](https://groups.google.com/forum/?fromgroups=#!topic/patternslib/ki_s0_ye2NY)
to specify dependencies which is a lot more flexible than the previous
syntax, and allows it to be used in other patterns. In particular the
validate pattern will use this as well.

This changes the syntax for the depends pattern in a non-backwards
compatible way.
