Configuration is now possible via cli arguments, so it is no longer
necessary to include my personal configuration.

Renames PullBlock to PollBlock and moves it to the SignalBlock in
QBar.BlockHelper.
The script block is now in linewise mode by default and can be
configured into polling mode with '--poll'.

Adapt wait time for additional block updates based on that (update
happens immediately after user interaction, while there is a longer
wait time for 'Pull'-updates).

Also rename 'blockScript' to 'scriptBlock' and move it to
'QBar.Blocks.Script'.

This reverses the control flow between 'Cli' and 'Server'
