Title: add a method to IPAddr instead of breaking a useful one

The monkey patch to `IPAddr#mask` in the [ecloud compute provider](https://github.com/fog/fog/blob/master/lib/fog/ecloud/compute.rb#L4-8) unnecessarily removes functionality from IPAddr in both [1.8.7](http://ruby-doc.org/stdlib-1.8.7/libdoc/ipaddr/rdoc/IPAddr.html#method-i-mask) and [1.9](http://www.ruby-doc.org/stdlib-1.9.3/libdoc/ipaddr/rdoc/IPAddr.html#method-i-mask). This pull request adds a method to IPAddr instead of breaking a useful one.
