Fix an overflow bug in pawns stormValue

These fields are defined as int8_t but values bigger
then 127 are stored there so that we silently overflow.

Fix bringing up all the fields to a sane int type. This
will increase memory usage, but apart from being safe, it is
not clear if code is slower or faster. Test is needed.
