Problem was introduced when adding header info.
To avoid the issue in future forward signals of the main plugin window
via condition and action edit widgets instead of relying on parent()
being the main window.
Almost every macro condition can benefit from having the option to
specify a time constraint.
Instead of adding it to each condition separately add it to all
conditions with the option of excluding it when registering a new
condition type.
Using int is an id was getting messy with more and more conditions and
actions beeing added.
It also made the order of conditions and actions in the respective
comboboxes unchangable as there was a 1 to 1 relation of index and id.
