With this patch, the dev can set <max-compression-ft> or <max-compression-m> in the set-file (or another
xml-file that get included from the set-file).
The code calculates also 'compression-m' for every gear.
If the 'max-compression-*' property is omitted, the code behave as before ('compression-norm' is the same as 'compression-ft').
