Summary: Local script variables not always initialized?

Initial Comment:
While looking for a different bug, I noticed that in
SCUMM games we sometimes ensure that all unused local
variables for a script are zeroed before calling
runScript(), and sometimes we don't.

Specifically, I noticed these cases:

In Actor::startWalkAnim(), when a walk script is invoked.

In ScummEngine::runInventoryScript()

When running the boot script. In this case we don't
even bother to give the script as many local variables
as we usually do.

Now, in all likelyhood these cases are probably still
well-defined. I assume the scripts never look at the
uninitialized variables. But maybe we should initialize
them anyway, just to be nice?
