Added long options and bash completion

[ms-jagadeeshan]

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..
