now that pockets have the same functionality as pads, the UIs can be unified:
- the position of the Offset widget in the UI is better in pocket, thus use it for pad too
- add missing tabstops for pad
- add missing tooltip for pocket
- update tabstops for pocket
This PR adds the functionality of pads to pad along either a custom direction or along an edge to pockets.
So with this PR Pad and Pocket are on the same level of functionality.
just a minor UI issue: when you decrease the width of the pocket dialog (e.g. because you have a small screen), the alignment of the widgets is lost. This PR fixes this by grouping the widgets in a grid.
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.
