Make RuleTable scrollable & DnD move instead of copy

Browse Source 
Having lots of rules in RuleTable may lead to an assertion failure on opening preferences dialog:

> assert "sz.x <= 1000 && sz.y <= 750" failed in
> PrefsDialog::PrefsDialog(): Preferences dialog exceeds max size

This change will make the RuleTable scrollable (as it is/was when creating many rules) instead of expanding the dialog size.
Further I had to fix the calculation of the clicked row from the given coords. Even without this proposed change for scrolling, the calculated row has always been the one above the clicked row - maybe this changed in wxWidgets 3.0.
Now it uses CalcUnscrolledPosition() which seems to work fine even without scrolling.

Last change is for drag and drop mode: rules are not being copied, but moved on dnd - I changed this to reflect this mode on the cursor while dragging an item.
