- Line 425: Update the ItemList class description to remove the obsolete claim
that wrapping requires ICON_MODE_TOP and fixed_column_width. Align it with the
wrapping behavior described in the note: wrapping depends on max_text_lines
being greater than 1 and a width constraint applying to the item.

Update the class description to match the new wrapping behavior.
Line 425 says text can wrap outside ICON_MODE_TOP and without fixed_column_width. The class description at Line 9 still says both settings are required. Update Line 9 so users do not follow the obsolete restriction.

This adds a
find_item_by_text()function to ItemList, so an item can be...found by text :D.It'll return the index or -1 when nothing's found.

Test project ^^^ here, script is attached and just demonstrates the basics.
This PR also addresses what appeared to be buggy or incomplete code regarding the Line Separation theme override on the ItemList:

This applies to the line separation within the list items, to be clear.
The existing behavior is odd, only enabled when the Icon Mode was set to Top:

...and when set to top, the behavior was off. For example, the separation between the lines would be multiplied by the Max Text Lines value:

...which I don't think made any sense. You can see the pre-existing behavior by setting Icon Mode to Top, setting the Line Separation enabled & a value > 0, then tick up Max Text Lines. You'll see the separation change thus.
This should be fixed up with this PR, and the Line Separation will also work regardless of the icon mode.
