Add option to specify the box name for downloaded boxes

[michaelheyvaert]

When I tried to import a box from a custom url I got the following result:

$ vagrant mutate http://<server_url>ms25_2014-10-31.box libvirt
Downloading box 31 from http://<server_url>/ms25_2014-10-31.box
Extracting box file to a temporary directory.
Converting 31 from virtualbox to libvirt.

would it be possible to add a --box-name flag to override the derived box name?

Would it be okay if ms25_2014-10-31 was the box name instead of 31?

The issue is that vagrant-mutate uses the regular expression (\w+).box$ to extract the box name but - is not considered a word character. I'll change the regex to ([-\w]+).box$.

this is perfect, thanks!
