Use uglifier-rails to set default js compressor for Rails

uglifier-rails: https://github.com/guilleiguaran/uglifier-rails

It can be moved to Rails Github account if you want

This can be included before 3.1 release?

@jeremy This is updated for master and can be cherry-picked to 3-2-stable branch

Please, if we are going to ship with uglifier-rails let's not make it depend on specific Rails versions. We don't want to have to release yet another gem on every rails release. We should simply depend on "uglifier-rails", "~> 4.0" and uglifier-rails should just accept any Rails version after 3.2.

[guilleiguaran]

@josevalim updated, uglifier-rails now depends on railties >= 3.2.0

[spastorino]

I was saying to Guillermo that seems excessive to have another gem for just this. All that uglifier-rails does is https://github.com/guilleiguaran/uglifier-rails/blob/master/lib/uglifier/rails/railtie.rb#L8.
Why not trying to push this to the uglifier gem itself or letting the user config this option in his own config files?.

[josevalim]

I agree with @spastorino but @jeremy was running into some issues iirc. There's a tradeoff here. It is up to you guys to decide.

@josevalim @spastorino this isn't going in Rails anymore, I will handle this in sprockets-rails and without creating a separated plugin (an initializer should be enough)

Closing.

cool
