Title: implements feature to list all gists

it works in this way :

`gist --list` or `gist -l` : will check if user is authenticated or not
> if user is authenticated : will list all `public` and `private` gist urls with description also
> if user is not authenticated : warn user to login, using `gist --login` and exit.

it also takes one `optional parameter` as `username`
`gist --list abhshkdz` will list all public gists of user `abhshkdz`, it resulted :
```
