[MvM] Bypassing certain upgrade cap values

[TrickyTrix935]

Description

Through a specific glitch method it is possible to bypass caps set in mvm_upgrades.txt for 3 specific upgrades on 4 different weapons, these being an extra "+10% Firing Speed" upgrade for the Force-a-Nature/Soda Poppper and an extra "+50% Ammo Capacity" upgrade for the Rocket Jumper/Sticky Jumper (I have linked a guide in the "Reproduction" section which explains how to do this).

Reproduction

1. Equip any of the following weapons: Force-a-Nature, Soda Popper, Rocket Jumper, Sticky Jumper
2. Follow the steps I have explained here - https://steamcommunity.com/sharedfiles/filedetails/?id=2114727049
3. "+10% Firing Speed" can be upgraded once on the Soda Popper and Force-a-Nature, and "+50% Ammo Capacity" can be upgraded once on the Rocket Jumper and the Sticky Jumper
