SGS HUD v 3.23 Release

In this release:
a) there are some changes for the fire inventory items (fireballs). If you intend to signup for Vulcanis, please upgrade.
b) you must keep the money bag for 12 minutes, instead of 10 (that is because it seems that 10 minutes might be slightly short).
c) there are a bunch of other minor bugfixes.
Upgrades are free and available at the entrance of the SIM.
This upgrade is optional.
