Fixed the CLOK chunk reading, so the parameters that
indicate whether the clock is the day clock (nancy5), or
completely disabled (nancy7) now get read correctly.
This includes a proper fix for the nancy2 softlock, as well as
a correction for which scenes need to be affected when
"fix softlocks" is enabled in nancy5
Due to the changes in the file format, nancy.dat needed
regeneration in order for the engine to work. The file now
contains data for all games up to and including nancy5.
