Calculation of file path may be performed in two different places -
first is the original location of the config file, second is on copied
one. Adding new option WRAPPER will take the same role as $CONFIG,
except it will be only parsed on copied configuration file.
An alternative would be to check existence in both places, but I'd like
to have it explicit.
Removing _kickstart_option in favor of _normalize_options method to
detect and replace relative paths with absolute ones. Dictionary with
changed options lands as a commandline switches for fs-uae during
execution.
To give user a possibility to choose what archiver he can use another
options was introduced for cd32 and archive wrapper modules. This option
will indicate what archiver should be used for compressing the save
state directories.
