Do not offer a default option when prompting for a user choice

[christianrondeau]

I suggest not offering a default option when offering choices to the end user. This will avoid cases when typing too fast ends up with Enter is not being preceeded by the desired number. It also shortens the output and makes less stuff to read.

There are currently at least two cases where a default option is offered.

Which version of vagrant would you like to uninstall?
 1) None [Default - Press Enter]
 2) 1.6.5
 3) All versions

Also:

Do you want to run the script?
 NOTE: If you choose not to run the script, the installation will
 fail.
 Skip is an advanced option and most likely will never be wanted.

 1) yes
 2) no [Default - Press Enter]
 3) skip
