Title: Adding support for full netmasks instead of subnet numbers

Hoi tehmaze,

I've added support to ipcalc for calculating the subnet number /xx using the actual netmask, because this was something I needed :)
If you want you can pull this from my fork, I think it's a useful feature for others people too. Please let me know if I should make any changes before it is ready for pulling.

Cheers,
Edwin
