Default extract method of compressed files

[iwfmp]

In the user menu, there's a lot of keys used to extract different formats of compressed files.
Using oh-my-zsh, I found a neat little ustil within the plugins folder called "extract", and designed to target all (or most known) compression formats and extract it effectively.

Just a suggesting to add the script as the default, and remove all others. Would make the user menu a little cleaner as starters.
