Small update for Pistol V01.00 sprite sheets

Hello people, small correction for the "Pistol V1.00" files, specifically the sprite sheets:

• Missing sprite-sheets for the "reload" and "empty" actions have been added.
• Previous files had different sizes for individual animations and some of them had misplaced order of frames, these discrepancies have been fixed and now all of the sprite sheets for the "Pistol V1.00" share the same size (80x48), position, and frame order.
• A very small change for the trigger in some of the sheets was also added, originally there was an animation of the trigger being pulled when the "reload" and "empty" actions started, now the trigger stays without moving all the time, just a small detail that was overlooked before.
