If the clipboard file doesn't exist (and it doesn't at system startup),
pyinotify will output an error to stderr. This situation is already
handled by also monitoring the directory itself for CREATE event. But
prevent error message.
non-GUI thread can't open new window in PyQt. So as a band aid print the
message to stderr in such case.
And while at it, fix filename in error message (it was clobbered later
while constructing stack trace).

This was broken since 8a91c90 "Fix block attach/detach", which changed
rows_with_blk list to contain VM qid, not name. One place was left not
updated.
Additionally document VmRowInTable.update parameters, as some of them
may be not obvious (blk_visible=None).

Currently:
* Create AppVM
* Remove AppVM
* Clone VM
* Start/Resume VM
* [...] VM
The first two are inconsistent. @bnvk and I agreed, that those should be changed AppVM -> VM for consistency.
And I add, if anything, it would have to be "Create TemplateBased-VM". Because currently, if you click "Create AppVM", you are asked in the next wizard if you wanted to create an AppVM, NetVM or ProxyVM. So the term AppVM is overloaded.
This commit fixes this.
xterm closes itself immediatelly when the specified command ends, so
wait for user reaction to give a chance to read the message (potentially
some error info). Also add some more meaningful window title.

The "default NetVM" is usually the first created ProxyVM which is
set by qubes-core during its creation. [1] If there is no ProxyVM,
there is no "default NetVM". Therefore, creating an AppVM and
launching its settings dialog raised AttributeError, because
get_default_netvm method returned None.
This can be reproduced by installing QubesOS without creating VMs
by installer.

Qubes manager used different logic what it considers as "running VM",
than qubes core.
Here it was "running or starting/stopping", while qubes core uses the
same as libvirt (isActive()), which effectively means "not halted" -
which includes also "paused" and "suspended". This creates a lot
confusion in which action should be available when.
The actual detected bug was about resuming paused VM. There was assert
"not vm.is_running()", while the paused VM _is_ running in terms of
qubes core.

QubesVmCollection is not thread safe. If for example update_table() will
be called during some long-running task (like creating or removing VM),
it will try to reload qubes.xml (so get read lock first), but the thread
already holds a lock on this file. This would result in "Lock already
taken" exception.
