Map Editor Enhancements

[thmsndk]

Having worked with the map editor on the new BEEginner Dungeon map here is a list of improvements I'd like to have made for the map editor.

• Show coordinates of mouse always as a little tooltip
• Area - show a size tooltip when dragging X by Y or the likes so you can see the pixel / row / column size
• tool tip on buttons for common shortcuts, e.g. deletion of Area, Line and so on
• Undo feature on ctrl +z?
• show gridlines ability to show gridlines on the map based on SIZE_X & SIZE_Y to make it easier to align things.
• rectangle select on tile chooser to change SIZE_X and SIZE_Y, perhaps a mode you enable to select
• select tiles /areas and move them by an offset
• zoom on scrollwheel, either on map, or in tileset view, depending on where you are hovering instead of toggling the mode in the tilset window
• SIZE_X & SIZE_Y should increment / decrement by STEP size using scrollwheel if input field is focus.
• ability to customize shortcuts, perhaps even templates you can apply so the shortcuts resemble other relevant editors.
• move my around by holding middle click?
