fastri 0.1.0.1

FastRI is an alternative to the ri command-line tool. It is *much* faster, and also allows you to offer RI lookup services over DRb. FastRI is a bit smarter than ri, and can find classes anywhere in the hierarchy without specifying the "full path". It also knows about gems, and can tell you e.g. which extensions to a core class were added by a specific gem.
