This makes it so the built-in scenarios do not require balm,
even though they are not legacy scenarios.
If we add balm to the scenarios, we can change this.
If I find balm in ZKR I will change it.
The picker is used in the special node dialog and also in monster abilities.
Some changes were made to the game as well:
* If the rotatable wall is used for a field missile or touch ability, there's no longer an option for the designer to pick an orientation. Instead, it behaves like the rotatable wall in a radiate field ability, selecting an orientation based on the creature's facing direction.
* The magic values sent to place_spell_pattern for direct damage were rearranged to match the order of the eDamageType enum. This should have no effect, since the core place_spell_pattern function is only called by the various wrapper overloads. It also simplifies the code quite a bit.
* The Protective Circle spell pattern is now exposed to the place patten special nodes. It can be used as just a radius 4 circle, but the effect of different layers of fields can also be obtained by specifying a field type or damage type of -1.
There is also a change to the dialog engine:
* Calling setText() also implicitly calls recalcRect()
The limit of 3 saved item rectangles has been removed - you can now add as many as you want.
However, the 1 per town limit is now strictly enforced.
The saved item rectangle is now shown with a cyan border when editing town.
In effect, this is a combination of two of the previous pickers:
the location picker, and the editable string picker.
This required quite a significant rework of how the tilemap places its children.
Currently it's only used in special node editing.
I plan to add its use in many other places too though.
It's used not only in special node editing (for Event Happens and If Event Happened?)
but also in the Townperson Advanced, Talk Node, and Quest editors.
