Handle properly window resizing

[joanna]

• When 'Show All' button is pressed, then window should enlarge to the max height (max height takes into account the Dom0's screen resolution)
• When 'Hide Inactive' button is pressed, the window should shrink to show only the active VMs (this seems to work now)
• When showing all the VMs, the scrollbar should be hidden as an indication that all the VMs are currently shown. Otherwise it might be misleading the user that there are more VMs.

And:

• When a new VM appears, and then manager window is not at the max height, it should autmatically adjust height to display this new VM.

What about allowing to resize the window vertically?

[joanna]

This would break the "show all running/all VMs" requirement, wouldn't it?

[aga]

Not necesserily. The default would be to show as many vms as possible. But I don't see a reason not to allow the user to shrink the window manually (with some restriction, e.g. show no less than 3 vms).
If you have like 30 vms, but want to see just a few of them (but not all turned on) it really wastes a lot of precious screen space.

[joanna]

Then you just switch to "show active"...

I suppose it will result in never showing all. And thus ommiting some info about templates that need to be updated.
