Remove translations provided by ActiveModel

[pelargir]

Alchemy defines several translations that are already defined by ActiveModel. One of these, the "confirmation" translation, is actually incorrect.

As of Rails 5, ActiveModel includes an "%{attribute}" variable reference in the translation, whereas Alchemy's copy simply has the word "confirmation." This results in poorly worded confirmation validation error messages.

For example, with a model defined this way:

class User < ActiveRecord::Base
  validates :password, confirmation: true
end

If the user doesn't provide a matching password confirmation, the validation error is:

"Password Confirmation doesn't match confirmation"

Whereas using the Rails 5 translation with the embedded "%{attribute}" variable gives:

"Password Confirmation doesn't match Password"

Which makes a whole lot more sense.

I've opted to simply remove the Alchemy translations entirely since these are already defined/provided by ActiveModel and there is really no need to redefine them again in Alchemy's translation file.

@pelargir Thanks Matt! Would you mind to remove them from the other locale files as well?

@tvdeyen I hesitate to remove the other translations since ActiveModel only provides the English translation file.

As discussed IRL we agreed to not remove the other translations.
