Added long options and bash completion

Changes:

Bash completion added
Long options added ( before passing arguments to getopts, loop through arguments and converts long option to short)
Translation and pronounciation fixed
Readme, help are added with long options
Note:
In linux, when placing bash completion under /etc/bash_completion.d/ it works fine
I don't know about mac, so i didn't changed installation part
Need to be done:
Installation code, which is compatible with linux and mac (BSD too)
zsh completion, fish completion etc..
