Handheld laser beams drain all energy crystals (Legacy)

[RingtailRaider]

Describe the issue
This is a legacy bug from the original version of Rock Raiders that could possibly be fixed in OpenLRR. I opened an issue about it after Baraklava mentioned it on discord.

The laser drain bug happens on more recent versions of Windows, since Vista or Windows 7 at least. A Rock Raider firing a laser beam causes all stored energy crystals to instantly become drained. The bug can sometimes also be triggered by firing any vehicle laser, or by slimy slugs emerging, though this does not cause it on all computers.

The way it has been fixed in the past is by decompiling the WADs, going to the Lazer { section in the CFG and adding a DischargeRate of 0.0. Removing the DischargeRate entry for other lasers also causes them to instantly drain all energy crystals. This does not happen when running the game on older computers or in compatibility mode, so it must be something that's changed in how computers interpret no entry for the discharge rate.

Steps to reproduce

1. Run an unmodded copy of the game without compatibility mode
2. Give a Rock Raider a laser beam
3. Make a monster emerge and turn Action Stations on
