New mirror and minor tweaks

i.e. Instead of cryptic
```
==> master: 0
==> master: :
==> master: 0
==> master: 7
==> master: :
==> master: 1
==> master: 7
==> master:  
==> master:  
==> master: 0
==> master: :
==> master: 0
==> master: 5
==> master: :
==> master: 4
==> master: 7
```
Show progress bar (though, it makes sense to hide curl output altogether).
