Show configured resources on the info screen

A new "Resources" section at the top of the info screen shows CPU
cores (with sockets for VMs), memory, swap for containers, and each
disk with its size. The disks are the same ones the edit dialog
offers, so cloud-init and CD drives are left out. A container without
a cores limit shows "unlimited".

The open info screen reloads after any guest job, so values edited
with e show up straight away.
