A simple interactive shell to invoke rake tasks.

Installation: put the 'irk'-script somewhere in your PATH, e.g. /usr/local/bin
Usage: where you could invoke rake, invoke irk instead, with a fragment of the name of the task you want to invoke, e.g.

% irk dump
   0) db:data:dump_dir
   1) db:dump
   2) db:mysql:dump
   3) db:schema:dump
   4) db:structure:dump
> 2

On the following prompt you can invoke a task just with its number. It is also possible to pass additional parameters:
> 1 FILE=foo OTHER=bar
