[Client] Preview Build #658C released

A new preview build of the ModMachine Client has been released. Build #658C comes with a completely redesigned module system, which is much more flexible and extendable than the previous one.
Also a new game module has been added to the client, which will be enabled within the next Workshop update.

Please note that this ModMachine Client release requires client templates generated with the (upcoming) Workshop build #259W or higher
