Updated docs to show faster installation
Updated docs to show faster installation

I just installed fastlane on a fresh Mac and it took longer than it should. By providing those additional parameters the installation is faster. This adds complexity.

Originally 
```
gem install fastlane
```
and now 
```
sudo gem install fastlane --verbose --no-ri --no-rdoc
```

We should probably do some additional testing on fresh Macs to see if it's worth the extra complexity
