[Feature Request] Export all referenced files to selected entity

[carmineos]

The idea is to add an option to export all the files referenced by a selected entity (maybe also extending this to all the other selectable items).

For example we select an entity and with one button click we extract:

• the .ydr/.yft/.ydd which contains the drawable
• the .ytyp which contains its archetypedef
• the required .ytd and all the parents of such .ytd from the gtxd tree
• the .ymap which contains the entity
• the parent .ymaps till there is not parent

It could be like a dialogbox which has all these options as checkboxes, it could either be an option to export directly from the toolbar/worldview or at least a way to copy all these referenced files to the project window and then save them from there.
