Remember command's optoins

Store options in file in home folder. 
Use just '.tddium' file, because when I save options and then user enter command without them I can't guess from what host use config file (e.x. '.tddium' or '.tddium.localhost').

Yes, but I have also test in spec/params_helper_spec.rb. I forgot to change file name and also there is one extra line in code(I will remove it)
