Added Shift+Mousewheel as faster alternative to E and R for tile selection
(had to change the undocumented and probably unused Shift+R action to Alt+R).
Allow applying element effects (numpad 0-9) to multiple selected tiles,
and not only one.
A new node does no longer have "NewPath" as default text when created,
which always forces the user to hammer backspace 6 times before own text can be entered.
Mods with a <Properties hasWorldMap="1"> tag in their XML definition
can now open a native world map like the original game.
Fixed an oversight that the world map visited area was
updated while the editor was open; fixed worldmap.txt saving;
removed the limitation that world map tiles had to be 256x256 -
all tile sizes work now.
Improved the builtin worldmap editor a little.
The game does now read _mods/#/data/stringbank.txt from a mod and merges
it with the main stringbank.txt, and uses _mods/#/data/worldmap.txt
as a full replacement.
Load _mods/#/[map|premap]_mapname.lua scripts to properly
initialize the Naija map token.
