just a minor UI issue: when you decrease the width of the pad dialog (e.g. because you have a small screen), the alignment of the widgets is lost. This fixes it by grouping the widgets in a grid.
It saves a lot of work if one can directly pad in any direction and OCC allows this.
This PR adds the possibility to define a custom vector for the padding direction.
Give a massive refactoring to Task dialogs for pocket and pad.
This commit features:
* Make Task dialogs for pocket and pad look nice in side-by side diff and
cross import features missing in each other.
* As a result it fixes several minor bugs.
* Gives a rework to the UpdateUI function.
* This one also fixes offset option support and migrates it to use unit
framework.
