1. Added option to save both binary AND txt version of words vectors
2. output_file is now the basename of all output files, different ouput files are generated including vocab, txt vec, binary vec and log with all run parameters

open issues:
1. Since we are using ouput_file as a basename, it's now mandatory and the user can't run word2vec without learning word vectors - need to give an option to run vocabulary creation only
2. We always write both txt vec AND binary vec, should be according to user's input
