Animate

[wasnotrice]

Here's a re-implementation of Shoes::Animate that accepts a Hash argument. The old syntax is still valid (this is similar to other methods like #oval that have multiple signatures). Use in the old way like:

animate 24 do
  # animation code
end

or with a hash:

animate :framerate => 17 do
  #animation code
end

At this point, no other options are implemented, so only :framerate makes any difference.

The merge commit here is really messy. Something bad happened in previous merges. The merge replaces the Rakefile (important!), the Gemfile, and some miscellaneous style work that I think was pulled into shoes/master???
