Semi-official patch: 4 minor fixes for GMDX addon

These files contains 4 minor fixes for 9.0.3:

-The stealth pistol will no longer have drastically reduced rate of fire after switching ammo types when the full auto mod has been installed
-The stealth pistol has its base damage increased from 8 to 9 as intended, but accidentally reverted during the GMDX v9 beta
-The inventory overlap exploit has been fixed, meaning you can no longer successively overlap items to get them to stack one atop the other
-The WP rockets in Sam Carter's cabinet in the 3rd visit of UNATCO have been moved so that the doors can actually be opened

Place the DeusEx.u file in "Deus Ex\GMDXv9\System", and place the 03_NYC_UNATCOHQ.dx file in "Deus Ex\GMDXv9\Maps". Back up the old versions first if you like.

These fixes only required 1-3 lines of code to be changed or a tiny map edit each, meaning I could package them up in short order without much fanfare while working on bigger things.
Expect news soon about my more extensive addon, featuring a some new and overhauled systems, reworked skills and perks, a brand new aug, and bugfixes/QoL changes which will make it into a more substantial 9.0.4 patch (not including my addon design changes).
