Map Editor: A feature for simple moving objects

[IIYAMA12]

Allows you to make some simple object movements in your map editor.

Changes:

• More object properties
• With the prop persistDefault="false", the data field will not persist when a default value is provided. Else this update would make all maps a bit bigger. I know persisting default values is generally better, but for this user case I find it unnecessary
• Editor preview of how the objects are moving from start to end
• Editor extension (file) modified to move the objects

Unknowns:

• What does the edf.edf file do? I am not sure if I have to keep that file in sync with the editor_main.edf file.
