Bracket Checking Tool

This script contains a tool for checking the number of opening and closing brackets in a scriptfile or line against each other. It is not flawless and there can be cases where it flags an error when there is none. For example when using a smiley in a /msg. This works the other way around, too. When you missed a bracket but, for example, a smiley in a /msg makes up for that missing bracket, this tool will not flag an error.
