Display RAILS_ENV in script/console

to avoid stupid errors (yes, we all need some sleep sometimes), I think we should display the current env in the rails console.

I've set this in my .irbrc file :

# Prompts
IRB.conf[:PROMPT][:CUSTOM] = { 
  :PROMPT_N => "[#{ENV["RAILS_ENV"].capitalize}]>> ",
  :PROMPT_I => "[#{ENV["RAILS_ENV"].capitalize}]>> ",
  :PROMPT_S => nil,
  :PROMPT_C => "?> ",
  :RETURN => "=> %s\n"
}   

# Set default prompt
IRB.conf[:PROMPT_MODE] = :CUSTOM

So it displays :

[Development]>> 1+1
=> 2

Maybe this could be included in ./railties/lib/commands/console.rb ?

Thanks
