Add ABORT button to update all adapters

[mcm1957]

Is your feature request related to a problem? Please describe.
not really - I started an update at the wrong system :-)

Describe the solution you'd like
Currently you have the possibility to update all updateable adapters at once. Thats comfortable. But once started there is no way to stop this process. At least I could not see any.

I would like to see a button to abort installation befor the next adapter in the list.

Of course, the active installation should not be interrupted, but I it should be possible to stop as soon as possible without leaviong an incomplete installation.

Describe alternatives you've considered
A forced shutdown should have stopped the installation too, but this would likely leave incomplete installation parts.
