Restore the old persistidents system from AC 1.0, since it's working as
intended - if used properly.
As a reminder:
* aliases created by "const" and "tempalias" are never persistent
* aliases created or altered by "alias" or "=" become persistent, if
the persistidents flag is set during that operation
* persistidents if false during the execution of almost all config files
during game start - those files can create aliases with default values
which will not be persistent (until changed later while the flag is
set)
* before saved.cfg is executed, the flag is set and stays set all
throughout the game - which means, that all changes (from menus, for
example) will change the altered alias to "persistent"
* exceptions for map or model config files are unnecessary, since those
run restricted and can't create aliases anyway
* exceptions are necessary for "late run" config files like those in
config/opt/
The new command "persistidents" may be used to manually set or clear the
flag. It also returns the current state of the flag. If used in a config
file, the flag is restored to its original value when the file ends
execution.
In short: only late-run config files (meaning: run after saved.cfg was
restored) may need to manually set/reset the flag. Use const and tempalias
where appropriate and clear persistidents before creating an alias with a
not-to-save default value that may be changed and made persistent later.
