This was consolidated for both EDuke and RedNukem frontends, put into a class with strict access control and the length limit was lifted.
The new class will eventually allow better localization control.
This broke the savegame reader which still assumed it was working on compressed data. Everything will now take the uncompressed path.
In-stream optional compression is not a good idea anyway, this can and should be done better.
Also: Why is the savegame format architecture dependent???
* saving of demos and savegames no longer mindlessly writes to the mod directory. All such access is now being rerouted through the special paths interface so that the game data can reside in write protected locations.
* refactored all occurences of klistpath except fnlist_getnames.
* do not allow CON scripts to write to arbitrary files. This is a massive exploit and can be used to cause real damage if someone knows how to play this thing - it's far easier than people may think! It will now write any such data to a special section in the main config which is safe and cannot be manipulated to write to random locations on the hard drive.
This removes all unused parts of the implementation and moves the rest to the InputState class for easier replacement later. All MACT is doing now here is to call the UpdateStatus function, the internal workings are no longer relevant.
This is a lot of changes in a lot of code because nothing here was abstracted into the sound system. :(
Hopefully most of the affected code here can be tossed out soon, it's not pretty.
In this case a different open function is used because this is normally files on the hard drive and not assets, so being able to have a different setup for finding them is important.
