Added a new option that allows you to increase the system image size for qemu
Created by: BrianOtto
I have added a new --image-size
option for qemu, as described in #551 (closed).
I feel like --increase-image-size
is a more accurate name for what the option does, but it seemed a little long to type. Let me know if you think it should be changed, or if you have any better ideas.
