add support for different htaccess file per environment

[martensc]

something like this may work:

# --------------------------------------------
# Overridden Tasks
# --------------------------------------------
namespace :ash do
    desc 'Copy distribution htaccess file'
    task :htaccess, :roles => :web do
        htaccess_env_file = "htacces.#{stage}.dist"
        if remote_file_exists?("#{latest_release}/#{htaccess_env_file}")
            run "mv #{latest_release}/#{htaccess_env_file} #{latest_release}/.htaccess"
        else 
            run "mv #{latest_release}/htaccess.dist #{latest_release}/.htaccess" if remote_file_exists?("#{latest_release}/htaccess.dist")
        end
  end
end
