Tokens and command objects reworked (part 1 of 2):

- fixed that copy effect doesn't restore original image after effect's end;
 - removed outdated availableImageSetCodes (all images auto-selected from tokens database now, related to #10139);
 - refactor command objects to use CommandObjectImpl;
 - refactor planes/emblems/etc objects to use MageObjectImpl, added copyable support;
 - refactor another game objects to remove some duplicated fields;
