Shadows of Amn XP cap

At the request of @JuliusBorisov I have made a simple adjustment to the XP cap for BG2. With this file in your override folder you will stop leveling just before you get high level abilities. This mod is designed for those who don't want HLAs available in Shadows of Amn. You will still gain XP in the background, but you will not be able to level up until you remove the xpcap.2da file from your override folder. Remove the file when you reach ToB, or whenever you feel like getting your HLAs, and you will instantly gain all the levels for any experience you earned above and beyond the cap.
