[17] have map editor create its own autosaves

[HurkWurk]

map editor currently overwrites the default autosaves. (it used to not use autosave at all). i would prefer that it use its own editor autosave set, rather than destroying game autosaves.

Autosaves are autosaves - they don't care what game you're running. A scenario, a campaign, freeplay, multiplayer, or the editor - they're all the same.

You can't treat the autosave slots as permanent storage - they're temporary for what ever running game you have going at the time.
