Title: show downloading progress when --verbose is on

this PR enable the downloading progress for curl and wget, so we can get clear about the progress while downloading the ruby source like this:

```
Downloading ruby-2.1.0.tar.gz...
/tmp/ruby-build.20140327132203.5768 ~
-> http://cache.ruby-lang.org/pub/ruby/2.1/ruby-2.1.0.tar.gz
% Total % Received % Xferd Average Speed Time Time Time Current

0 14.3M 0 99345 0 0 703 0 5:57:25 0:02:21 5:55:04 174
```

(oh shit, 174 bytes per second)

I don't know if the quiet policy is by design or not, unluckily the network in china is really sucks on downloading ruby :( , maybe a progress could make us life better on sucks network?
