Saving with F5 does not remember loaded file name

[Loobinex]

When you load a map, then save it with F5, adikted will create files without a file name, just file extensions.

Steps to reproduce

1. Start adikted
2. Ctrl+L to load
3. type a number, for example 20, and press enter to load the map
   (optional) make changes
4. Press F5 to save the map
   -> notice the levels folder now has a list of files without a name, and map 20 is not saved

Workaround:

1. Start adikted
2. Ctrl+L to load
3. type a number, for example 20, and press enter to load the map
   (optional) make changes
4. Press Ctrl+S, then type 20 (or another number) to save the map
   (optional) make further changes
5. press F5 to save the map
   -> it now remembers to save the map to map number specified in 4)
