 - ensure rake db:test:prepare is called on rails 2.3 projects

Rails is defined when loading tasks from a plugin.
This should now fix it.

- rake test:coverage:units now only shows output for models, helpers, and libs

…f controllers

should work with ruby 1.9.2 and rails 3 release candidate

… removed from ruby 1.9.2)

I find the descriptions added to the generated tasks are too dirty for my liking

hopefully this will be a starting point for a more general RcovRails::RcovTask
that encompasses the whole process
(currently it still relies upon a bit of manual hacking)

just do it if someone tries to run the rcov task

now works with rails 3 gem dependencies
