Fix for Merb Slices using directory name as slice name

Stupid Merb Slice Fix

if File.exists?(slice_name_file = File.join(__DIR__, 'slice_name'))
  contents = ''
  file = open(slice_name_file, "r") 
  file.each_line do |line|
    contents += line
  end
  file.close
  contents.strip!
  slice_name = contents unless contents.empty?
end
