Add option to transform gamenames

Configuration file $XDG_CONFIG_HOME/lgogdownloader/transformations.json can be used to set rules for transforming gamenames.
New subdir templates: %gamename_transformed% and %gamename_transformed_firstletter%
"--list transformations" can be used to show transformed gamenames
