(svn r2136) - Fix: [ 1174313 ] terrain hotkeys nonfunctional in scenario editor (D,Q,W,E,R,T,Y,U fltr)
- Fix: 'L' no longer opens ingame terraform bar in scenario editor bar, but the land generator one
- Feature: [ 1095110 ] Create Lake and draggable Create Desert tools (initial implementation GoneWacko), also added sticky buttons to land generator and town generator
- CodeChange: moved around some of the draggable tools, demystifying them
- CodeChange: change CmdBuildCanal to allow for XANDY dragging not only X or Y (only scenario editor)
- CodeChange: add some more enums to sprites.
- TODO: merge most of the ingame and scenario editor land terraform code. This can only be done after OnClickButton function is changed so it also includes the backreference to the widget being clicked, postponed to after 0.4.0
