reduz 75755beeee
Implement textual ext/subresource IDs. 
* Friendlier with version control.
* Generates pseudo unique IDs, to minimize conflicts when merging, but still
  user readable (so, not UUID).
* Eventually will also allow to have more precisely named sub-resources in
  imported files.
* This will allow better reloading on changes (including resources already
  loaded) as well as better keeping track of changes on the DCC.
* Keeps backward compatibility with the old formats.
* Binary and text format version incremented to mark breakage in forward
  compatibility.
