Subject: added saving static variables to engine snapshots for SP game engine
X-Git-Tag: 4.1.1.0~196
X-Git-Url: https://git.artsoft.org/?a=commitdiff_plain;h=2558f6e933a3b70682bd2437c00065842bd3cf2c;p=rocksndiamonds.git

added saving static variables to engine snapshots for SP game engine

There were a number of static variables holding game engine values
that were forgotten to be saved in game engine snapshots for the
Supaplex game engine.

Storing and restoring these engine values was added by this fix.
