Stub fields in Rails model generator

[ches]

Greetings Pete,

I've updated the Rails model generator to create some defaults for fields, like so:

$ rails g model Foo title:string date:datetime
...
$ cat spec/support/blueprints.rb 
require 'machinist/active_record'

# Add your blueprints here.
#
# e.g.
#   Post.blueprint do
#     title { "Post #{sn}" }
#     body  { "Lorem ipsum..." }
#   end

Foo.blueprint do
  title { "MyString" }
  date { "2010-10-09 16:44:25" }
end

Thanks for creating Machinist :-)

Hey Pete,

Just perusing my old open pull requests and saw this, so thought I'd bump it. Still using this little hack in my projects :-)
