This includes:
* Allowing the details area to scroll should the parent dialog not be long enough.
* Scaling all displayed sprites to 144x144 while maintaining aspect ratio.
* Forcing extra width so all mainline unit names have enough space to appear.
* Removing the unused 'minimal' definition. Might be added back later.
* Fixing the borders. The internal widgets shouldn't have outside borders, since borders
should be set for the widget instance in a containing dialog.
This also adds the necessary changes to said widget to allow single-unit stats display.
It still needs to be expanded somewhat. Right now it contains the minimum required for
the attack dialog.
Add search_recall_list=only to search the recall list, but not the map
This is intended as a more clear way of doing 'x,y=recall,recall' and omitting search_recall_list. Note that search_recall_list=no with x,y=recall,recall produces a useless [role] which only runs the [else] block(s).
Add reassign attribute
Optional attribute, default 'yes'. If 'no' then do not re-assign the role if a unit already has the role. If 'no' and no unit has the role, the role is still assigned.
Refactor auto_recall as a sub-tag
Instead of a yes|no attribute, if there is an [auto_recall] sub-tag then recall the unit from the recall list. This acts as a [recall] tag without any StandardUnitFilterto which we add id=$unit.id and issue the recall.
There seems to possibly be an internal issue with the slider (and more generally, the
scrollbar implementation form which it inherits) where is min/maximum_positioner_length
equal an even number, sliders with an even number of options will reach max value.
Setting it to what, in this case is 1 below the actual width of the slider image (15)
means both even and odd-numbered sliders will reach max value, however the edge is cut off.
Attempting to set the right_offset to 1 and using the above off value for the positioned
width means only sliders with an odd number of options reach max value.
The magic numbers in this commit seem to give the widget enough space to reach the end of
the slider and max values regardless of the number of options, but the internal widget dimension
calculation should perhaps be investigated in the future.
This caused an error message and recruiting to be abandoned when the
recruit rushers Micro AI was used for two different sides in the same
scenario. It was only presents since the AI refactoring done during
1.13.4+dev and did not affect any release.
